Doomsday FTW! He fuxored Superman's supersphincter, and if batman was around would have used him to wipe himself clean(if he hadn't died aswell, obviously).

Superman by a lot.

superman is gay because he would get his ass kick by Gandalf the grey and harry potter i mean harry potter,poor form may i remind you superman weakness is not only kptonite but magic powers

ehh...I'll take a fully armored F-35B and a B-2 Spirit please...

Batman actually keeps (or kept) a ring set with kryptonite, that he conveniently uses in an issue where Poison Ivy charms Superman into attacking Batman and co.
I don't remember where he got the ring, but when I read the comic I was like; "Ahhhh Gaaawwwdd..." it was a little silly imo.
And; yes Superman is way too powerful, much like Chuck Norris or Arnie in movies, you know they're gonna get resistance (and a huge showdown with main baddie) but nothing is gonna stand in their way for long.
Batman has gotten his ass handed to him dozens of times, being beaten to near death at least thrice and his companion (Robin) actually gets killed, very rare to have sidekicks killed in hero comics.

batman hands down.

Batman simply because there hasn't been a really good story that gets into Superman's head (that I'm aware of). We get to see Batman's human frailties and many people can easily relate to him because he's not perfect while Superman maybe because he's alien or whatever we never really get to see a lot of that. Plus the fact that Superman is so powerful that it makes it hard to find interesting villains for him to fight without it being just another ridiculously powerful being.

I just realized; seeing most stories about Superman, he seems to have no personality at all.
Then again, it could be unfair comparing him to what is probably the deepest character in the roster.

If written well... Superman. Normally Batman.

Superman actually can be a very deep character as he's the strongest man on the planet, yet also one of the most moral... few people play on this though rather treating him like a one dimensional perfect man then playing on the constant moral struggle to just say screw it and wipe everyone out.

Batman has his problems as well. He's packaged as "Just a normal guy without superpowers" yet often times he does feats through just outright stupid means or through ridiculious plot devices just to show that Batman is right up there with the rest of the league.

Honestly i'd say Wonder Woman is a better character then both.
