And yet Loki hurt him with a little dagger. To the point that he had trouble landing a few moments later.
The Hulk punch thing, I am not sure about, mainly because we don't know how strong Hulk was at that moment. The best domestration of Asgardian strength is in a deleted scene from the first movie. Volstagg helping the child retrieve their ball.
Unlike Thor, Superman hasn't had to compete with different writers and script based injuries yet. We will see what happens when Batman shows up. I expect plenty of stupid when that happens.
