Well, if IronMan could stay far away enough, he could just blast the Hulk into submission. But if the Hulk got too close, he would crush IronMan like a twig.
Hulk, he can jump super high and you know how bullets and rockets can't hurt him so Hulk would win. He an also survive super high frequency Sonic Blasts!
I would also have to say Iron Man. He seems more "equiped" to take out the Hulk, but if Hulk got the 1st hit Iron Man is "bye bye".
That was what I was supposed to say. I think Iron Man is in the position to win since he has advanced weaponry and he can fly around the Hulk. I do agree if The Hulk gets to him he's history.
