Since I posted this, I will go first and tell you who I think will win.
My choice is Vegita, hands down.
Vegita is a master tactician, he is ruthless and cold-blooded and will go to any length to win. Vegita is a skilled master at martial arts and is able to move at speeds faster than the human eye can see. Vegita's armor is indestructible, able to take a Kaio-ken x4 Kamehameha (a planet busting attack) by Goku and still able to stay intact, this armor is able to grow and stay with him, even in Sayain-ape mode.
Vegita also possesses various attacks such as Big Bang Attack, Final Flash and the Gallick Gun, the latter two being planet busters. He also posses the ability to use ranged energy attacks such as his Ki-ball attack that would keep Hulk at bay. We also have to consider other factors such as Vegita's ability to go Super-Sayain and even stronger (i.e. Majin Vegita)
We also must remember that Vegita has the ability (when he had a tail) to go Sayain Ape, which increases his strength 80 fold.
Ok, I could go on and on and on, but I am at work and if I don't want to get in trouble, I have to get back to work
