Diddo on the peach - I have a big limb from the neighbor's tree that should be ready come spring time. I've never used Peach, so can't wait to try it.
Double Diddo on Mesquite - I just don't care for the flavor.
I use chipped oak for fuel in my smoker, and unless I'm doing poultry for the Mrs's, it will have either hickory or apple, or both in it! I have used pecan and really liked it, but can't seem to find it here. Guess Bassman has it all bought up
That pretty much does it for me. Had a bad experience with maple one time, and like chinese food - when I find something I like, I stick with it!
