Bending an indestructible metal as if it were a pipe cleaner doesn't exactly demean the fact.
I wouldn't go so far as to say outright that Hulk's fist is stronger than adamantium at all. If Hulk's fist is put on a table and attacked, it'll get cut and heal and what not. Adamantium won't even be damaged. In that respect it's stronger. Hulk is wielding his fist though, with no one wielding adamantium, it's pretty useless. That's my opinion.
Like that guy said in the Conan movie, steel is only as strong as the hand that wields it. Thor has a pretty strong hand and he's wielding Uru. No easy task and Thor at his best could take Hulk, IMO. If it's common Hulk Vs common Thor. I back Hulk.
An excellent fight would be Maestro Hulk Vs Full Power Thor.
I'd buy that for a dollar.
