The Joker.

There is alot of controversy on who was the "best" Joker. This cannot be proven no matter how many facts you have to back your little theory up. Cesar Romero, Jack Nicholson, and Heath Ledger all did great in their interpretation of the Joker. Cesar Romero and Jack Nicholson played a more comical Joker in their roles of the movie. Heath Ledger on the other hand intended the Joker to be a dark, maniacal psycopath of a killer. On a personal note, I favor Heath Ledger's Joker, and I'm alot more interested in a dark fiend character rather than a comical villain. Therefore this cannot be determined who was "the best" or who "played him better" since each of these great actors portrayed the Joker in their own sense.
