As a dbs AND marvel fan, read WW hulk if you don't think so . In DBZ , Hulk's power level would be infinite, no one could tell his limit, basically Broly on STEROIDS
As a Saiyan, Broly can fly, teleport, move at super speed, and emit powerful blasts of energy, whereas Hulk's primary power is his strength. His healing factor gives him an edge, but other Marvel characters have beaten Hulk in the past, meaning broly could feasibly overpower him as well
You've no idea what you're talking about. Hulk's primary power isn't his strength, it's his rage. The angrier the hulk gets, the stronger the hulk gets. A non angry hulk already shook the multiverse.
