West was a different Batman for a different time. Doesn't mean he's any less good than Bale or Keaton.
If you want to compare him to the character he played I guess he was fine. But the batman he played was stupid overall. I guess if you just compare the two actors, they're about equal. But I still give the edge to Bale. I felt he captured everything batman was supposed to be just a little better than all the rest.
