I'm pretty certain that if Superman was fighting withing sight of the Sun, he would win. Wolverine does have andamantium claws and a skeleton and all however, but if I'm right there was part of a comic I saw where the Hulk bent some of the metal, so Hulk could probably beat him, but not without some damage. Now with Superman versus the Hulk, Superman has a whole lot of powerful powers and all, but the Hulk can heal ad regenerate very quickly, and I don't think he has an upper limit to his strength. Conclusion: I have no idea who'd win.

Being a Batman fanboy I choose 4, but in reality, Hulk could give Superman a run for his money but Wolverine would be destroyed relatively quickly.

Didn't the Beyonder say the Hulk can achieve infinite Strength and Rage. So basically Superman could do what he did to Doomsday, but the difference if the Hulk could get mad enough to break time and space to get back to the fight against Superman till he finally got mad enought to snap Superman in half, but by then you're talking about ending the universe. If it was just a fist fight with no flying and mano to mano, the Hulk would get his green butt handed to him for the majority of the fight till the hulk started catching up to Superman in strength and speed then I believe he would start to surpass him till the Hulk was cracking the Earth in half to push the Big S's face into the back of his skull.
