The Batman relevance argument.

You can't use logic when talking about Superman. I hate that he's even in the same continuity with other superheroes, especially those like Batman who are at least in the same solar system as logic.

 On the other hand, Superman is inept. With his powers, he should have solved every problem in the world long ago. Also, a cynical and brilliant person like Batman would have contingency plans in place. No doubt that he's probably bought up as much kryptonite as he could find. If Superman acted first, however, Batman wouldn't have a prayer. Only in a situation where Batman could lay a trap could he possibly succeed--and then only because Superman is dumb.

Superman is anything but inept. The characters powers and intelligence are anything but useless. Any kryptonian has the ability to outhink an earthling and their intelligence is off the charts. Lex Luthor spent so much time trying to be like Superman and destroying him that he never got to understand what it means to be Superman. Once he understood that the world made sense and he shut up. If you combine all of the powers of the JLA together and levels of intellegence technically they wouldn't need batman. Hes the only odd man out and he's really the only liability on the team because he's injury prone compared to the rest of them. Again, in these books it comes down to the writer, but if we've seen the show, we know better.
