My two favorites;
Michael Keaton - love this version.  Keaton in/out of the mask, the suit, 
the car, the Danny Elfman theme, Gotham, the supporting casts. 
Adam West - Love this show.  
The car.  Silly, endlessly entertaining, no matter how many times I've seen an episode.  I LOVE how how it's played straight (especially West) no matter how absurd the lines or plots.
After that....
Kevin Conroy - Crisis on Infinite Earths on the CW Arrowverse stuff.  Even though he wasn't in the Bat-suit. 
Christian Bale - I really liked him as Bruce Wayne.  I'd like his BM more if they hadn't gone with the distorted voice.  I HATE his car (unless your talking about the sports car he wrecks late in #2).   
 
Lewis Wilson (Batman, 1943)/
Robert Lowery (Batman and Robin, 1949) - they're 1940s serials.  They are what they are.  Wich is still better than 
Ben Affleck - He really only had that one really good fight sequence in the warehouse in BvS.
Val Kilmer - Bleh.  Though the car was sorta cool.
George Clooney - Even more bleh.  And the car.
