Unless Carol was depowered in last months, he wins this fight. She-Hulk is currently a character that has very bad appearances currently. Including situation in which she couldn't lift more than 80 tons (which is PIS or it comes from her calm state, IDK).
@mrtrevorguy: Faster and more skilled, Yeah I could by that but I was under the impression that they were around the same area of strength. I haven't read a hole lot to do with She Hulk but I remember her being pegged around the 75 - 80 ton range and in this one book I read ( I cant remember the name for the life of me) She Hulk and Grey Hulk teamed up (she was unaware of his relation to her, though suspicious) Grey Hulk showed off some serious savage power and it actually startled and some what scared her.
