I would assume Hulk would win because in World War Hulk he defeated all of the x-men including Cyclops, Wolverine, Nightcrawler, Beast, Storm, And many more mutants. Weapon x only has a few mutants powers and Hulk killed almost every single one.

Hulk would win. Onslaught beat the X-men,Fantastic four, and the Avengers all together and Hulk still managed to kill him. I think that Hulk is probably the most powerful comic book character ever. (Next to Superman and Thor.)

Typically Hulk does win, often because their not trying to kill Hulk.
R1 and X
Definitely X-men because they are stronger and better.

The T-X would burn and melt the T-1000 easily. So the T-X would win.
