Purely by feats, Comic Thing should win.
Look at the hits Kurse landed on Thor that stunned/bloodied him.
Comic Thing is stronger than that, and faster too (they were throwing punches at each other at normal speed basically).
How do we know comic Thing was stronger than Kurse?
The best strength feat Kurse has in that movie is chucking that rock at Thor about 100-150 feet. That rock is pretty big, massing in at about 150-200 tons (eyeballing based off of Google).
I'm no Thing expert, but if Thing can tussle with Namor and the like, he's certainly capable of outputting more force than that (also there are certainly feats that exceed "chuck big rock 150 feet")
But we don't know that that's Kurse's limit.
We don't, but we know that level of strength is certainly enough to stun and bloody Thor. After Kurse punched him into the mountain side, Thor was dazed, and the rock throw laid him out on the ground (Thor was on his hands and knees and was struggling to recall the hammer).
During the ground pound, Thor couldn't even fight back.
The damage clearly wasn't great but it shows the level of strength needed to hurt Thor. Kurse's theoretical upper limit is irrelevant.
It's very relevant. We know Kurse is strong enough to hurt Thor, but we have no idea how strong he is. Kurse could be class 100. He could be class 50. He could have a Skyfather level of strength, who knows. You seem to be just randomly stating Kurse isn't as strong as Thing.
Thing has generally been shown to hover around the 70-75 ton class. Only, when he was pineapple Thing was he then Hulk class. He has a long history of being beaten by the Hulk, one story of him nearly killing Hulk. Majority of the time it's been Hulk smashing the shit of of Grimm. And I like him. And Thing struggled to keep a fire truck from falling off a bridge.
We know in the movies Thor had a good time fighting with the Hulk. But, didn't get smashed on by the Hulk as he did by Kurse. But, we did see the strength differences between movie Hulk and Thor that he had to call upon Mjilnoir to keep up with Hulk.
Hell, Thor had Mjilnoir and couldn't match up to Kurse. From the beginning to the end o f the fight he dominated Thor. He flew at him and was bitch slapped out of the air by Kurse who had his back turned. And later when Thor summoned Mjilnoir again. It was bitchslapped and knocked away easily by Kurse.https://m.youtube.com/watch?v=ZJneSSYTZFo
And even on the Ranged attacks alone. Thor has Grimm's number.
