We don't think so, no. They're beloved guitars for a reason - the quality and sound p[roduced is excellent. However, they're not the only great brand out there. Similar brands include Taylor and Gibson - you can see more about them in our Fender Telecoustic review or our Gibson Les Paul Custom vs Standard Comparison. With any classic guitar brand, you are paying for prestige and history as well as the actual guitar itself. The Martin D-shaped guitars have been used by some incredible guitarists over the years. However, in this case, we really don't think they're overhyped - they're just well-loved. They definitely cost more, so it's worth thinking about trying one first if you're hesitant to spend a lot of money.
