From a psychological stand point, Jones, because he just says things, and leaves it at that.
DC is more of the type to either qualify his trash talk, or explain it in depth, instead of just saying it. More a testament to how eloquent DC is, but still, in the old school game of trash talk, I'd say Jones has the upper hand.
And like the previous poster said, "you think I'm just gonna let you kill me?" was kind of corny. You just say something like, "Try it, bitch, I'd fucking break your neck", or something like that.
Either way, we all know DC can be a bit of a cornball. His trash talk has no basis on how badly he's gonna beat the breaks off of Bones. Jones is also a cornball, but he won this round.
