Non sick WB has no feats. If you mean prime WB, he may have a chance if he holds up to the claim he can destroy the world. Otherwise Juubi Obito takes this.
Naruto wins more offten then not. Luffy's ONLY chance it to beat Naruto before he can go into BM/BSM or wait till he is completely drained. Otherwise Naruto takes this.
Zoro wins with CoO haki to dodge Sasukes attacks and long range slashes.
Admirals stomp. The kages have no way to hit them, unless onoki best showing can do something.
Law wins with so many versatile haxs it isn't even funny. Nagato wouldn't even see most of what he can do coming.
I would bet on Itachi taking this one. He just has more going for him then Sanji who is just a melee range fighter.
Current Garp and Current Sengoku get stomped. Prime may have a chance, but again hype and featless so it would be only speculation.
