Martin was around long before Guild, and Guild doesn't even offer any "sustainable wood" products (although who knows what Kaman will do eventually -- can you imagine a D-55 with a plastic back??) I always believe you have to go with what speaks to you.
Martin make some awesome guitars at ridiculous prices these days. However, I bought my daughter a Martin Starter guitar last fall, and I was astounded how wonderful this guitar sounded EVEN THOUGH IT WAS A PLASTIC GUITAR.
Got it for under $500, and it played like a dream right out of the box, and since it is a material like Formica, you don't have to worry about dinging it.
