@Dirk_R , Everybody has their own preference. Warmth of Mahogany, Chime of Koa, Base and clarity of Rosewood. Compared to each other (not an easy thing to do I am guessing in Ketchikan), at a store that handles Taylor, is the best way to see which.
Me, I know I am staid in my ways, and I love the tones Koa adds. I don’t own a Mahogany guitar (except for necks), and do also really prefer Rosewood to a lot of other tone woods.
All bodies and sides are “layered” (read laminated or ply), tops are solid. The Rosewood has a solid Sitka Spruce top. The Mahogany (Layered Sapele an African member of Mahogany’s family) has a Mahogany top. The Koa has a Koa top and layered Koa Back and Sides.
Good luck, with the progress you have made, I bet whatever you choose will be a fun addition for you, and will encourage you further. (As I was looking these up, I notice there are two other models, but have never seen one of those.)
