In most comic storylines, it's a bit of a toss-up. Sometimes Hulk has raw power on his side, but Thor has his magic hammer and godly abilities. So, it depends on the specific context and plot.
Well, it's not a straightforward comparison. Hulk has immense strength and can get stronger as he gets angrier. Thor, on the other hand, has Mjolnir and the powers of a god. Different scenarios can give either one the upper hand.
The answer varies. Hulk's strength is often unlimited, but Thor's powers are more diverse and include control over elements and divine magic. It really depends on how the writers envision their battles in each comic.
