Taylor and Yamaha both make nice guitars.
I think the fact that you feel the Taylor feels better in your hands, is real important. So a good guitar tech can get the Yamaha to play great. But even if you had a good set-up (more money) and the Yamaha plays as good as the Taylor, the neck is still not going to feel like the Taylor.
The poly finish on the Yamaha is most likely more durable,
but to my ears, I've always found the tone on thicker finished guitars is not as open as the tone on lighter finished guitars. The satin finish may not look as good, and may wear, but unless you are Willie Nelson, it's going to last a long time. (Willie's still plays fine with the holes in the top
)
They are both quality guitars, you just have to decide what you want out of them. If one makes you want to play more, that's the one to get.
Wish you good luck in your decision and welcome to the forum. Let us know what you decide.
