even though im a big hulk fan, goku outclasses him here in speed and numerous amount of attacks, if goku decides to slug it out then hulk wins but goku is a skilled fighter and knows how to fight with his power set, goku>hulk unless he can go WB in which xase hulk slams a mountain on goku. But yeah it will become thor vs superman in which case thor more often than not imho, or a draw.
I honestly see Superman edging the win. Superman is a physical powerhouse and he has the speed to smack Thor around. I don't see Thor withstanding too much punishment at SS. At least not average Thor. High-End Thor with uber damage-soak? Sure.
If hulk can go WB it quickly becomes a 2 v 1 in team marvels favour, thors magical attacks and wbh sheer power would beat superman, it just really depends on hulk being able to go WB
