DC has more punching power, is a naturally thicker guy and as much as people want to make out like he's some pussy, he grew up way rougher than Jones, he's seen some shit. However Jones is potentially a legitimate sociopath, I'd have to go with him, they're pretty evenly matched though, neither guy is going to beat the shit out of each other. I would've loved to see them compete at open weight, DC looked better at HW than he did at LHW, even though he was short and fat he always looked rather gaunt in his face at LHW weigh ins.
