I see that people thorough this tread only bring the fact that wolverine fights the Hulk.. the Thing is not simply a weaker version of the Hulk. It seems to me Wolverine does well against Hulk(or Wendigo) because they're just beasts looking to smash. Big dumb animals following a bouncing ball without any strategy. Their process of thought is follow wolverine with the eyes and try to grab or hit at him. Ben is a trained fighter, and even though his strength is not as great it is still vast. Has the hulk ever hit wolverine with a well placed punch? has the hulk tried grappling wolverine? dropping his weight on him? a series of different kinds of attacks? e.g, thunderclap+heavy object throw+pin to the ground+(add any other move of dozens that would work)... These are all things that Grimm can do because he isn't some half mindless beast. Also, wolverine slashing his face and then the fight being stopped doesn't mean he won. If that was a win then no winner would have been injured ever. You can't judge the likely outcome of a fight between these two on the base of two previous fight that can barely even called fights, and I'm also considering the fight when Ben knocked Logan on the head, that wasn't a fight either. I think the battle could go either way, and it would be a good one.
I just think the fight could be revisited as it seems to me it is closer than most might believe, Cheers.
Thing... he's not a big dumb strong guy like others they mentioned( savage hulk, rhino).. He knows spiderman and what he can do, he can get him with a miture of tunderclaps and tossing heavy stuff fast. On the other hand it doesn't seem like spiderman can hurt the thing.. I mean he seems more durable than he is strong.
