Martin will always be the cream of the crop for me. Such a warm resonant tone. Perfect acoustic guitar in my mind.
I never got the love for Martins - old school Guilds blow them away - regardless of price. I do like the finish and detail on the Martins, but that's about it.
Taylors I have never liked. Tinny, brassy, not for me.
I love the Grand Symphony models and I don't find them tinny. But, then again, I like Ovations, too (is that blasphemy?)
Gibsons are nice, but the hummingbird always sounded too boomy to me.
I find the bass in Gibsons to be kind of muddy. My every day player is an old Guild D-35 with a broken shoulder. I gave $100 for her. She sings, though.
