What kind of wallet do you like the best?

Question

I'm looking to get a nice wallet and Nautica makes some pretty good ones. They make a bi-fold (folds twice) and a tri-fold wallet (3x). If you've had both types, which do you like better and why, and also what are some other pretty good brands?

I wan't a small, comfortable wallet so I'm thinking the trifold might be best but not sure...
