I have a handful of types that I don't care for, but outside of that have no favorites between the ones I like.
The concept of having "favorites" boggles my mind. I like variety, and appreciate differences. If you have a "favorite" anything, have you thought about why you have labelled it as such - is it just because some yahoo asked for your favorite color when you were in elementary school and you thought you had to pick one to give a "correct" answer, so applied the "favorite" concept to other things, or is it really your favorite whatever?
