Hulk main powers are
Superhuman strength, durability and regenerative healing factor
Thor also has these 3 powers but in addition has MANY more
This is the reason that overall Thor is more powerful than Hulk in the Marvel Hierarchy
In reality Thor does not need god blasts or hammer blows or anything like this. He can simply use telekinesis and raise Hulk in the air, then do what he pleases.
If for some reason Hulk and Thor are fighting hand 2 hand so only their powers of strength, durability and healing are taken into account, then in my opinion there is no reason Hulk cannot beat Thor.
Hulk's powers increase with anger, stress etc but Thor's powers do not increase the same way. Thor has a certain level and can also increase strength by tenfold.
So the question is what is the limit to Hulk's power increase. If there is truly no limit then eventually Hulk would kill Thor.
Different writers do all different stories throughout marvel universe full of inconsistency.
There is no reason why Hulk cannot be the physically strongest in Marvel Universe, as this would not make him the most powerful overall at all.
Nevermind Gods, there are a whole host of characters who could beat Hulk despite his strength. Anyone with reality warping, telekinesis, magic, energy manipulation etc etc
