Storm and Magneto are largely ineffectual here, unless Superman's body contains metals Magneto can manipulate.
Hulk is strong, but lacks the speed to contend with Superman, and with this Superman being more than willing to BFR, he should be able to remove Hulk from the fight. His biggest problems are Thor, and the fact that he's fighting four people at a time. Even as fast as he is, he could get snagged by Thor, or distracted and tagged by Hulk.
Team, imo.
