im sorry to say it but spiderman cant beat wolverine or sabertooth, he might have a chance with deathstrike. Wolverine powers has been enhance also by apocalypse. Every encounter that wolverine and spiderman gets into, spiderman always shows a sign of fearing wolverine and getting owned by him also. During that fight with creed, spiderman had the aid of punisher, creed could have killed spiderman on there 1st encounter in that book,you see the thing about spiderman fighting each of the 1 on 1 is that with his encounter with wolverirne, wolverine shows mercy but sabertooth is a different story, he will try and kill spiderman.
When spiderman gets owned by other fighter besides his enemies, people always says bad writing, its not bad writing, he also got owned by x-23, now watch people say that he was holding back because she is a girl, or he was underestimating her, no he just almost got killed, with a set of claws at his neck.
spiderman has a very hard time with very skilled fighters, look how daredevil handles him and look at the fight between him and electra, she was toying with him. If spiderman was to fight any one of these fighters and had a chose to choose, i hope he choose wolverine, a person who cares about him and that would take it easy,instead of sabertooth because sabertooth will make short work of spiderman.
