I also think there's an innate 'mystic' element that's only found in gods. For example (Possible Thor: God of Thunder spoiler) Gorr the God Butcher talks about god blood, so there must be some distinction between just a powerful being and a god?
Brute strength is Hulk's main thing, whereas Thor has a lot of other things going for him (mjolnir, weather manipulation, lightning etc) so if Hulk loses a lot, he loses his "strongest" title as well. And Thor is kinda the only guy strong enough to put up a fight against him, so sadly he's the one that has to get beat down to show Hulk's power.
I think Thor would win more often,, simply because he has more powers available to him. I respect that overall Hulk gets stronger than Thor though, 'cause that's his thing. If their battle is long, difficult and brutal then either way is fine by me. (as long its not just jobbing)
But seriously, I think Thor's team has this, due to Wolverine, The Flash, Doomsday, Green Lantern, Martian Manhunter, Aquaman and Thor himself who are all insanely powerful, as well as the cunning minds of Doom and Batman.
I think Supes team is lacking slightly in comparison, with the exception of the Hulk, WW , 'Shazam' and himself.
Really looking forward to this movie. Loving Thor's hair.
Excited to see the return of Loki and how the brothers interact, although I hope the film doesn't become overly Loki-centric (as much as I love the guy). I'd love to see in-depth character development and awesome feats from Thor.
