It has to be Batman . Remeber he is a detective rather than a superhero.
The problem with Superman was he became too strong and invincible.
Stages of the comics became too comical and occasionally farcical as they had to create new weaknesses to bring him down to earth.
Batman is much more vunerable and therefore has a much better backstory and much more interesting problems.
