[Avengers: Infinity War] What if Hulk had fought throughout the whole film?

Say after the fight with Thanos, Bruce retains complete control over the Hulk.  Tony, Dr. Strange, Wong, and Bruce are facing the Black Order. Instead of the Hulk refusing to come out , he bursts onto the scene. How does the film change?

Not significantly, as Thanos was already capable of easily beating the Hulk.

Whatever incremental pressure Thanos would feel when fighting the Avengers would probably still allow him to get off his snap. Thor wouldn't aim for the head just because the big guy is there.
