Wow! I never thought of it this way... also Sue shouldn't be depicted as weak because she is a girl because in the comics she is often referred to as the strongest and most powerful member of the fantastic four.
Wolverine loses to cap it he's unable to fight him (that's the case with most heroes) or
Wolverine wins because cap did something that really gets him mad. If wolverine is mad, then nothing separates him from you and your death. And he has his healing factor, so no matter what cap does eventually he must submit.
However, most likely cap would win because wolverine probably wouldn't want to face him.
