Ok, I’ll throw in my list:
I mostly agree with OP’s reasons on all but Bale and Clooney. While Bale was certainly great as Batman, I did not buy him as Bruce Wayne. Dark Knight Trilogy was great entertainment, but it was too grimdark. Clooney on the other hand was great as Bruce Wayne and the movie had the cartoon sillyness of the old tv series, and although it was a bit too silly, I loved it way more than Dark Knights.
So far it looks like Keaton is far in the lead, followed distantly by Bale. I'm a little surprised that Keaton's lead is so great, but I certainly would pick him as my favorite non-animated Batman to date. He had a remoteness and quirkiness that both humanized him and showed the damaged psyche of the character.
Bale was fine, but a little bland coming from the actor that had such a bravura performance in American Psycho.
Still waiting for someone to do a live action movie of Arkham Asylum: A Serious House on Serious Earth.
