I'd say Bourne. 47 was an excellent assassin, but he relied a lot on prep and advanced equipment. He wasn't even in the room when the African guy was killed at the beginning, and most of his kills (like the elevator and the bathroom) involved ambushes and disguise (like at the end). I'd say Bourne's just as accurate (nailed a perfect shot while falling several stories), and he's far faster in H2H.
