too close to call. i actually think thor might be a tiny bit stronger, but orion is the more skilled fighter imo. and he has a speed advantage as well. durability is pretty close to even. i'd say dead split or 5.1/10 to orion. be really interesting to see red orion come out against warrior mad thor. they would likely kill each other in such a case.
lol this is spite against Thor. Orion could practically one shot him. Hulk HAS one shot Thor physically. Tutinax gave him two of the worst beat downs ever. Taurus humiliated him physically. Superman, Hulk and Orion are roughly physically equals. There's no way Thor has a chance in hell in this kind of match.
