Superman or Batman?

This burning question came up on Jim Winter's blog. I commented:

[A]s problematic as Superman is (World's most powerful hero can be brought to his knees by a strange green rock that—despite its strangeness—is apparently readily available to any self-respecting criminal), I still have to back him over Batman. Bruce Wayne may be a badass, but I wouldn't want the neuroses that go with that. Clark Kent is symbolic of the good that can come from a positive outlook. Cynicism and pessimism may be hip, but no solutions were ever reached through negativity. Heroes by definition must believe they can be of help. Optimism, however disguised, is part of the job description.
