Batman. Why? Because although he was portrayed very poorly by one George Clooney, he was never so lame as to have been played by George Lazenby (On Her Majesty's Secret Service) or Timothy Dalton (License to Kill). Clooney may have sucked, but not to that level of craptitude.

On top of that, Batman is just a better character. He's the ultimate badass. The fact is, he is capable of beating damn near any character in the DC Universe solely becuase of the fact that he is satanically cunning and paralleled in intelligence only by Lex Luthor. He can take Superman down, and he doesn't even have any powers! Most likely, he could take out Green Lantern, and GL can split atoms with his power ring. Batman is the man. Bond is awesome, but he's not invincible, and he's got nowhere near the level of intellect that Batman contains. On top of that, Batman cheats, rigging his battles in so many ways that there is nearly no possibility for his opponents to win.

Batman is my choice, easily.
