The whole "Superman is too strong argument" is such an uninformed statement and pretty much confirms that someone knows nothing about the character.
Anyway, in my opinion it's Spider-Man. Well, the Spider-Man of the past 30 or so years. That character has literally done everything he possible can and he's now an adult who behaves like a freshman in high school. He's annoying, whiney and has never grown up. I've been saying for years that Marvel needs to kill off Peter Parker and let a new actually interesting character take up the mantel.
