Burton's Batman is cooler than Joker
Couple of times I would read that Burton cares more about the villains than the Batman character and that may or may not be true. But the fact is no matter what, Keaton's Batman always remained more cool than any villain he was facing. When the movie was over no one thought that Nicholson joker upstaged the Batman but the other way around. Nolan's joker completely and I do mean completely upstaged Bale Batman.
