As for right now Superman has displayed a higher level of power. You can't top shock wave producing punches. I hope Hulk and Thor get a massive power boost in Avengers 2. The big Krytonian in Smallville helping Faora felt like the Hulk during the Smallville fight sequence. I hope Joss Whedon sees Man of Steel and ups his game on the spectacle side. Synder has Whedon beat on the visuals but Whedon has Goyer beat on the writing.
Exactly. What do you think was Superman's most significant show of strength that Hulk or Thor can't match?
