Sound Quality Comparison
The most important thing that will determine the tone of an acoustic guitar is the wood. Let's take a look at the differences between both .
Woods Used in Both
Spruce has a light color with tight grain patterns. It's very stiff but relatively light. It's known for producing a well-rounded tone with a broad dynamic range. Find out more about Spruce.
Mahogany is a fairly rare wood nowadays. It's used mostly for bodies due to its relatively lightweight. Gibson popularized it with their Les Paul guitars during their golden years, so this wood has a lot of good reputation behind it. The most expensive type comes from South America and it's still used by Gibson even today. Find out more about Mahogany.
Woods Used in the Yamaha STORIA I
Nato a hard and dense wood similar to Mahogany, but cheaper and not quite as hard. Tone-wise, it's also similar, but it doesn't have quite the same attack as Mahogany.
It's a hard wood with a chocolate color that is often used to give an elegant finish. Since it's quite expensive and rare, it's mostly used for guitar tops. Find out more about Walnut.
Woods Used in the Martin D-18 Authentic 1939 Aged
Ebony is a high-end wood, so it is not cheap. It's only used for fretboards because it's also very heavy. It does an excellent job as a durable material while looking elegant. Find out more about Ebony.
Winner: Martin D-18 Authentic 1939 Aged.
Electronics
The Yamaha STORIA I comes with a preamp that allows you to connect it to an amp, unlike its competitor. This allows it to have more versatility and sound quality if you want to record with it or play live.
Winner:Yamaha STORIA I.
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 Yamaha STORIA I compares to the Martin D-18 Authentic 1939 Aged.
Country of Origin
The manufacturing country can tell a lot about the build quality of an instrument. The Yamaha STORIA I is built in China while the Martin D-18 Authentic 1939 Aged is made in United States.
China has a bad reputation when it comes to building quality. However, times have changed and now respectable brands use China's cheap labor to build good instruments for a lower price. Don't discount a guitar only because it was built in China, but also expect more quality from countries like Korea.
The United States is considered one of the best electric guitar manufacturers in the world. A guitar made in this country is supposed to have world-class quality control. Nowadays, guitars made in other countries can beat some of the ones made in the US, but most of the time, this country offers the best you can get. Of course, that comes at a price.
Winner: Martin D-18 Authentic 1939 Aged
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 Yamaha STORIA I 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 Martin D-18 Authentic 1939 Aged comes with a Bone nut. It's a type of nut found in high-quality instruments. They sound similar to Ivory since they give a lot of sustain and a bright sound (at least when striking open strings). The only problem they can run into is that you may get a bone piece that simply doesn't sound as well as others because that's just how natural materials are.
Winner: Martin D-18 Authentic 1939 Aged.
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.
Tuners
Both come with regular tuners. The Yamaha STORIA I's are Open Gear Champagne-Gold while the Martin D-18 Authentic 1939 Aged's are Nickel Open Gear - Aged

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, both have a nut width of 42.9mm (1.688'').
This is within the most common range of nut widths for a 6-string guitar. It offers a good balance of string separation at the nut. It's the size that most guitarists prefer as it gives them just enough space to play open chords without muting the strings, but without spreading the strings too wide and making bar chords difficult to perform.
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.
The Martin D-18 Authentic 1939 Aged has the longest scale: 25.4". The Yamaha STORIA I is only 25" long. This is a 0.4'' (10.2mm) scale length difference.
This longer scale means that the strings need more tension to get in tune. This is good if you want to avoid fret buzz, which can happen when the strings are too loose and touch the frets while vibrating. This is especially important when playing in lower tunings. This will also let you reduce the gap between fretboard and strings (low action) to make them easier to press down. However, this higher tension will also make it harder to perform bends and vibratos as the strings will feel stiffer.
This also means that the frets have a longer separation between each other, so this will make it harder for people with smaller hands when playing some chord positions.
Another characteristic of a longer scale is that it makes the guitar sound 'snappier' or brighter. This is due to the extra separation between harmonics and overtones produced by the tension. This influences tone more than any other factor (except the pickups).
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 Yamaha STORIA I has a C type of 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.
The Martin D-18 Authentic 1939 Aged, on the other hand, has a Vintage neck. This means that it's thicker than most modern necks, and makes it a better fit for playing chords and slow solos. Some people prefer this type of neck because it gives them a better grip thanks to the extra mass. Still, the vast majority prefer a thinner, faster, and more ''modern'' neck.
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 Yamaha STORIA I's fingerboard radius is smaller, which means it's more curved than the Martin D-18 Authentic 1939 Aged'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 Martin D-18 Authentic 1939 Aged.
Still, both tend to favor soloing over chords, so if you're looking for a guitar for playing rhythm, you might want something else with a radius closer to a Stratocaster's 9.5''.
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 Martin D-18 Authentic 1939 Aged favors large hands more than the Yamaha STORIA I.

Fret Size
Both have a Medium fret size. If you like feeling the fretboard when you play, but also appreciate some easiness to press down the frets, this size offers a good balance for that.
