1. Conroy
The voice from Batman the animated series, and other animated movies. He's easily number 1 because he plays both Batman and Bruce Wayne to perfection. You hear the personality, you understand his mental, what drives him. You can tell when he's angry and when he's in a good mood. The animated series was the best on screen version of the comic book character by far.
2. Affleck
Everything Conroy brought in animation, Affleck brought in live action. I feel like he just studied the character more than his live action counterparts. We knew Affleck is a serious actor, and we know he's an avid comic book reader. It's not outside the belief for me that he knows more about Batman as a character than anyone else on this list. I feel like he channeled him in a way others couldn't. The scene with Alfred where he's talking about is there's a 1% chance Superman is bad, we have to treat it like 100% was some Batman logic at it's best. The post credit scene to the Snyder cut, was a classic Batman v joker dialogue. It's a shame he never got the solo movie
3. West
Responsible for bringing many fans to the table with his wacky cartoonish version that really did feel like a comic book TV show. It definitely was a lighter tone, but it set the stage and built the foundation for most of the things we know about Batman. We saw the detective, the escape artist, prep time, we saw the father/son relationship with Robin. We got familiar with the exaggerated villains in his rouge gallery. It is still a fun show to watch if you ever have time. Same bat place, same bat channel.
