Well, let's see....
Voice? Keaton is still king. I think using a modulator is ultimately a very safe decision that doesn't take any real creativity. And say what you will about Bale's voice, but at least it's identifiable. Can't say the same in Batfleck's case.
Batmobile? West, Keaton, and Bale all had better Batmobile's. Those three Batmobile's helped redefine how you saw the Batmobile, IMO. Batfleck's car is just the Burtonmobile crossed with the Tumbler. Once again, another aspect of Batfleck that doesn't really stand out compared to other Batmen.
Suit? One of the two aspects that Batfleck has over competitors. Comic accuracte, tough looking, and seemingly flexible. Not my ideal Bat Outfit, but after 30 + years, a live action Batman's finally wearing Gray in his Outfit again. Can't complain about that.
Fighting? The second thing Batfleck has over the others. The Warehouse fight is the only scene in the movie I was actually impressed with.
Batcave? Meh, no better or worse than others, I think.
Alfred? Jeremy Irons is a good Alfred...but until he gets better material to work with, he's below Michael Caine for me.
Gotham? One of the more unremarkable ones.
Comic accuracy? Adam West remains the most comic book accurate Batman. He is light hearted Batman come to life.
Intelligence? West still squashes everybody, and Batfleck seemed kinda foolish at times. I'd still say Bale is smarter, too.
Overall performance? Not as iconic as West, Keaton, or Bale. There's room for improvement, though. He managed to steal the show in BvS, but BvS is a mediocre-to-bad film, and he's the one aspect that filmmakers seemed to actually care about. The first live action Batman to steal the show in a movie as high profile and/or good as TDK or B89 will probably be THE definitive Batman, IMO.
