Superman would win because superman would just rip wolverine in half .
I think that Wolverine would kill Superman because he can just use his claws and stab Superman in the heart. Or cut his throat. Tons of things.
Superman would win because Superman has only 1 specific weakness so he can easily drag wolverine and watch him disinagrate which means that Wolverine cannot heal back again.
Wolverine would win, unless you are Wolverine. Then he'd still win. If talking about the animal, you would win.
Wolverine can heal himself so Wolverine would win.
Anyone who isn't a hopeless Marvel fanboy would conclude that Wolverine, healing factor or not, would be left a greasy stain and a wisp of vapor while Superman wouldn't even be scratched.

Wolverine wins.

If the Jedi was allowed a lightsaber, then they would utterly mutilate wolverine. If it was a no-weapons allowed brawl, it woul be equal, if it was a cage fight then wolverine would win.
Wolverine hands down.
