To be fair, whenever Hulk "pulverized" Hercules, there was always some reason why Herc wasnt at his fullest, almost all of them were in periods when Herc had lost his godhood or was actually trying to diffuse the fight and calm the hulk down by soaking damage... When he had it, and was willing to fight, their battles were very much a close call, as much as his classic Thor fights were.
I can see an unworthy Thor being easily put in a similar position to a mortal hercules. The gods are weird because their strenght, like Kieron Gillen once said, is similar in scope, but different in quality from the Hulk. Theirs is a mithological, magical kind of strenght, while hulk is science based. Both have the ability to achieve the impossible in that category, but by very different routes... We will see how the unworthy thor matches up with a worldbreaker soon if Pak delivers on his promises in the next Hulk issue
Good points. Also important to note is that the Hercules who fought Wonder Woman was not at full power and they fought near evenly, so I would see a full powered Hercules as Thor's physical equal:
