While playing with the hulk can give you a decent thrill, playing with banner is just down right horrible.
While playing with the hulk you'll be destroying basically anything in your path. You can take pipes, rocks, cars, and other various items. The enemies don't really give you a challenge. They can't even touch you.
With doctor banner you'll be doing some stealth missions. Now don't be thinking metal gear stealth. This part of the game is pretty much horrible. There's no action. Unless you want to kill your self. Yo just run around solving puzzles. Sadly these parts cannot be ignored. Unless you get a cheat to skip the levels. I recommend you do. Reason being those parts of the game are really dull.
All in all, hulk isn't a bad game. Rent it and beat it. Playing with hulk is satisfying, but with banner it just sucks. So hulk fans give this one a shot. Action fans, rent it, and skip to the hulk parts.
