Nevertheless, when it comes to choosing an instrument, you should pick the one more compatible with your personal style. Still, below we'll try you to give you our results as objectively as it's possible to help you decide.
Sound Quality Comparison
The wood used in an electric guitar or bass is not as important to determine the final tone. However, some people prefer specific wood types, so we'll take a look at those first. Then, we'll take a look at the electronics to determine the versatility and sound quality of each instrument.
Woods Used in Both
Maple is one of the most popular necks for good reasons. It is a strong wood that is relatively cheap to make and looks beautiful. The highest quality maple is the hardest that comes from North America. Find out more about Maple.
Woods Used in the Ibanez RGRT421
Jatoba is a hard and dense wood that emphasizes the mid-lows, giving a fuller, more round sound than, for example, Mahogany. However, it also has a lot of clarity in the top end. Find out more about Jatoba.
Nyatoh has been replacing Mahogany for guitar building. It's fairly hard, durable, more sustentable and common than Mahogany. Find out more about Nyatoh.
Woods Used in the Ibanez JS140M
Basswood is a lightweight type of wood that isn't as expensive as other popular choices for guitar building. It gives more power to the mid-range frequencies. Its color can vary from pale white to light brown. Find out more about Basswood.
Winner: Tie.
Pickup Configuration
Both pickup configurations are HH. Double Humbucker (HH) is the choice for people who want a fuller, more round sound with tons of mids and lows. Humbuckers also get rid of the hum noise that plague single-coil pickups. They can work out for almost any genre going from Djent to even Jazz.
Pickups Quality
None of these use a specialized pickup brand for their pickups. Some of the best guitars on the market come with pickups from brands like EMG, Seymour Duncan, DiMarzio, etc. You might want to replace your pickups eventually if you want to get the best sound out of any of these instruments.
Both use Passive pickups. This is what's used for most music genres. They have a regular output and will serve you for both high-gain and clean tones. The alternative (Active pickups) offer a higher output that is mostly used for heavy music.
Winner: Tie.
Versatility Comparison
Some instruments offer you more ways to explore your creativity than others. Below you'll find how both compare when it comes to versatility.
Switch Options
The Ibanez RGRT421 gives you 5 switch options while the Ibanez JS140M gives you 3. This means that the Ibanez RGRT421 gives you more options to find the right pickup combination for the type of sound you want to achieve
Only the Ibanez JS140M comes with some kind of pickup modification: Coil Split.
Coil Split lets you disconnect one of the pickup coils. When used with humbuckers, it turns them into single-coil with lower output and cleaner tone.
When evaluating versatility, we also take into consideration bridge and neck joint type, number of frets, switch options, amount of pickups and more.
Winner: Ibanez JS140M.
Final Sound Quality Scores
Build Quality Comparison
When it comes to build quality, we like to take into account everything used to build the instrument. This includes materials, hardware and the quality control expected depending on the country where it was built. Let's see how the Ibanez RGRT421 compares to the Ibanez JS140M.
Country of Origin
The manufacturing country can tell a lot about the build quality of an instrument. Both in this comparison where made in Indonesia.
Indonesia is becoming the most popular country for guitar building because they can make good instruments for a low price. Some people think that they're 'the new China' when it comes to build quality. But the truth is that Indonesian guitars are more consistent, although Chinese quality has improved a lot in the last few years.
Winner: Tie
Nut Material
If you want your guitar to stay in tune and sound good, you need a well cut nut. Nut quality can be inconsistent even when comparing two copies of the same model. The best way to make sure you're nut will be well done is by getting a nut made by an expert company like TUSQ or Micarta.
The Ibanez RGRT421 has a Plastic nut. This is a low-quality nut that you might want to consider upgrading soon. Bone and TUSQ nuts are the best for guitars with a fixed or simple tremolo bridge.
On the other hand, the Ibanez JS140M comes with a Locking nut. Instead of a regular nut, this guitar has a locking system that will lock down the strings at the nut, preventing it from getting out of tune. It removes one of the disadvantages of tremolo bridges, tune stability.
Winner: Ibanez JS140M.
Fret Material
Most fret wire is made of nickel silver. This material eventually wears down after a lot of use and most instruments end up needing a complete fret replacement. However, some expensive models come with stainless steel frets. This is what you should aim for if you can afford it.
Unfortunately, none of them come with stainless steel frets.
Winner: Tie.
Bridge
The perfect bridge for you will depend on your playstyle because they all have advantages and disadvantages. However, some bridges are more expensive—like Floyd Roses and Evertunes—and thus add more value to a guitar.
The Ibanez RGRT421's brige is a Fixed. It's a simple bridge that is very beginner-friendly since it doesn't require any set-up. You can swap strings easily. It might also give more sustain since it doesn't have complex moving parts that make the strings lose vibration. However, it doesn't have the same versatility as a tremolo bridge.
On the other hand, the Ibanez JS140M's is a Edge Zero II. This is a cheaper version of Ibanez's Edge Zero bridges. It comes with the same locking stud bolts that lock down into the body and provide better stabilization, and with easier adjustment of the springs without having to remove the backplate thanks to a thumb-screw. However, the intonation in this cheaper version will require additional work.
Edge Zero IIs that come with the ZPS3 Zero Point system have two extra springs that help return the tremolo to the neutral position faster. These bridges offer tons of versatility, but they also require more work than simpler tremolos to set up.
Since we need to be objective, the most expensive type of bridge will be the winner of this section. In the end, this doesn't matter if you're not going to use the bridge for its original purpose, so choose the bridge that fits your playing style better.
Winner: Ibanez JS140M.
Tuners
Both come with regular tuners. Both come with Ibanez.
Winner: Tie.
Neck Joint
Contrary to popular belief, the difference in sustain and tone that some neck joints give to a guitar is simply unperceivable—if they're all well built. However, some of them do have advantages over the others.
The Ibanez RGRT421 has a Neck-Through neck joint. This neck is a lot more resistant and lets builders give the neck joint a more comfortable shape for soloing at the upper frets. The disadvantage is that they're more expensive and that if you damage your neck, you can't simply replace it like with bolt-on necks.
On the other hand, the Ibanez JS140M comes with Bolt-On neck joint. This neck is joined to the body by 4 bolts that you can simply unscrew. This allows you to replace the neck or take it off for travel. It's the most common and cheapest way to build a guitar.
Winner: Ibanez RGRT421.

Final Build Quality Scores
Playability Comparison
Let's now compare their playability. Bear in mind that the instrument will feel different depending on your hand size and play style. That's why you should always test before buying. But if you can't or want a second opinion on it, we can still take a look at each of the important measurements of the instrument for you. This way, we can predict how easy a guitar might be to play, or how different it will feel compared to the other.
Remember that, even though the difference might seem small, every inch counts when it comes to feeling of the instrument in your hands. Any variation can completely change how comfortable a guitar feels in your hands.
Nut Width
The nut width will affect the separation between strings at the nut. In this comparison, the Ibanez RGRT421 has the wider nut with 43mm (1.693'') vs 42mm (1.654''). This is a 1mm (0.039'') difference
This means that it will be more difficult to do bar chords on the Ibanez RGRT421, especially closer to the nut. However, it's also easier to play without muting strings accidently. This favors people with big hands.
Scale Length
The scale length is one of the things that influences playability the most. This is the distance between the nut and the bridge and will affect everything from low action allowance, difficulty to perform bends, fret separation, and even tone.
In this case, both have a scale length of 25.5".
This is the scale used in most Stratocasters. It's slightly longer than the typical 24.75'' size found in Les Pauls, and it's one of the main reasons why Stratocasters have such a bright sound in general. A longer scale also means that the strings will have higher tension. This will help you get lower action without suffering fret buzz, which will also be helpful when playing in lower tunings without having to increase your string gauge.
However, this also means that there will be more separation between frets, which can make it more difficult to play. Also, bending the strings will require more strengths due to the increased tension, but remember that a tremolo guitar will offset this difficulty.
Lastly, remember that you can also affect the tension of the strings by changing your string gauge. You can use a thicker gauge for more tension and a lighter one for less tension.
Neck Profile
No single neck shape is better than others. However, most people tend to prefer a thinner necks because it doesn't get in their way when playing fast and most hand sizes can adapt to it pretty well. However, some people still prefer thicker necks for a better grip, especially if they have big hands.
In this case, both have different neck shapes:
The Ibanez RGRT421 has a Wizard type of neck. This is thinner than most C-type necks. It won't get in your way if you want to play fast solos. It's not as slim as 'Super Wizard' necks, so it might fit you better if you don't like ultra-thin necks.
The Ibanez JS140M, on the other hand, has a C neck. This is what you'll find in most modern guitars. Most people feel like the thickness of a C neck is simply the less intrusive one for playing fast, while at the same time allowing you to grab the neck easily for resting if you want to.
Fretboard Radius
Most guitar fretboards are not flat; they usually have a curve or arc across their width. A curved fretboard will make it easier to perform chords without muting strings, while a flatter one will make it easier to play single notes, which is good for bending and soloing in general. The best fretboards have a compound radius that varies across the fingerboard, but they're not common since they take a lot more work to build.
In this case, the Ibanez JS140M's fingerboard radius is smaller, which means it's more curved than the Ibanez RGRT421's. This extra arc will make playing chords easier in this model. You won't be as likely to mute the strings, especially if you have big hands. However, playing single notes and bending will be easier on the Ibanez RGRT421.
Hand Size Comfortability
Everyone has a different hand size, and that's why it's recommended to try a guitar before buying, even if others tell you that it's comfortable to play. However, we can know whether a guitar favors small or large hands just by knowing its exact measurements.
And after taking into account the scale length, nut width, neck profile and fretboard radius, we can conclude that the Ibanez RGRT421 favors large hands more than the Ibanez JS140M. But it's still more comfortable for people with small hands, as you can see in the score meter below.

Ibanez JS140M:
Fret Size
The Ibanez RGRT421 has Jumbo frets, which should be taller than the Ibanez JS140M's Medium frets.
Some people prefer taller frets because they result in more sustain since the strings get pressed cleanly without interference from the fretboard. However, if they're too tall—like Jumbo frets—, you might change the pitch of the strings accidentally if you press too hard because you won't be touching the fretboard with your fingers. This is also why some guitarists with a heavy grip prefer smaller frets. They like to feel the fingerboard to avoid pressing down too hard and getting out of pitch.
