A couple of the main things to me are comfort...and sound...acoustic guitars can be deceiving...if you played a few and liked the feel of that one in your hand and your fingers working the things you do on the neck and the way it feels sitting on your leg it's probably a good fit...then the sound , does it project well or do you have to play the hell out of it to get any projection out of it?...just compare it from those perspectives cos a guitar you write on is something you spend quite a bit of time with. when I was a kid it was more about the look...ha...be well.
