Of Course The Hulk since he has Unlimited force wich depends on his level on Anger, maybe in the beginning of the fight Gladiator would be even with Hulk but at the End Hulk would kick butt because he would only get stronger and stronger as the fight progresses.

That would be a good fight but in the movie "Hulk vs Thor" Thor shot a bolt of lighting at Hulk and the Hulk didn't even get hurt. So since all Raiden can do is shoot lighting then the Hulk would win.
