Have to go with Bond. Even if you only consider the Daniel Craig Bond, there's a coldness there that basically doesn't give a fuck about doing anything but getting the mission done at any cost. Bourne still has a conscience of sorts.
I guess to some degree it's actually sociopathic behavior that Bond displays, which is not something that should be considered admirable. Still, as long as it's for good and not evil...
You have to admire the Bourne movies though. Until I saw them I didn't realize how many different things could be used as a weapon (like a textbook). And it's not even in a hammy kind of way, since once you think about it you realize it would actually kinda work.
Edit: And it's hard to deny that the Daniel Craig Bond movies were influenced by the Bourne style. He suddenly became a lot more physical than he had been in any previous Bond incarnation. The Connery Bond survived mostly by cunning. The Craig Bond just breaks people in two.
Sean Connery was so devilish as Bond, it was masterful. But I think Matt Damon worked a lot harder in the Bourne series. I watched some of the Bourne extras and they explained how Damon prepared. I somehow doubt that Connery did anything too difficult. They probably had doubles do that stuff.
Yes, a whole lot of the Bond stuff was super hammy, and it gets a bit much! The Bourne trilogy steers clear of that, fortunately. And there are only 3 of them, right? Much more tidy.
The Bourne Trilogy > Mission: Impossible (as bad as no. 2 was) > The Bond Movies (disclaimer: I haven't seen any of the pre-Golden Eye Bond movies; don't tase me bro!)
Jason Bourne is definitely the more interesting character out of all three. Also, I'm kind of biased because I love Matt Damon and everything he does.
I'm a Damon fan too. Watched
The Departed again a couple of weeks ago. Damon's work in that was stupendous!
Sean Connery is way hotter than Matt Damon.
Actually, I heard he's kind of a jerk... but I don't want to believe it.
