I'm more of a Hulk fan, but Superman is probably the most powerful character ever created. Remember, he can shift time and space due to his speed. He's has a host of weapons/abilities at his disposal; think he can't take a Hulk punch? That's all hulk can do -- beat on him; doesn't help if Superman can withstand anything that Hulk's got to dish out.
Additionally, he's beat much bigger players (i.e. Galactus, etc.) than Hulk. Also, Superman was given immunity to kryptonite in one series, so that can be done too.
And the Hulk madder/grow bigger thing is bullshit. Does't exist. Not in the comic books.
