I like Wick more, which is why it sucks to have to admit Bourne would win.
In movies the main characters always end up in a one on one fight to the death (or submission) with no guns and when it comes to hand to hand Bourne seems to have a good bit of edge on Wick.
So, movie winner is Bourne. If it were "real life" it would never get to a hand to hand fight and Wick would be the victor.
