Definitely '89, though Returns has the better Bat-emblem. The only ones I really dislike are the Clooney ice suit, TDK/TDKR, and Affleck's later looks. I still wish the grey would be used more often, though.

The ice suit is blue and silver

Out of those, The Dark Knight

The Batman/Pattinson suit.

The suit’s not entirely black though. It’s predominantly gray.

From the flash

Dark Knight
