Jones is the much more skillful fighter at all. But Lesnar is just so much bigger and knows how to use his strong wrestling. He's sensitive for accurate and powerful striking such as his fights vs Velasquez and Overeem proved. He simply got his *** whipped. But there's no way you could compare Jones' punches to those of a heavyweight, he's really not that impressive with his overall striking although his elbows are vicious stuff. Honestly although he's 10 times the better fighter than Brock I think it would not be enough to take the win. I see Lesnar bringing the fight to the ground, nailing him to the ground with his superior size and weight and winning by TKO.

Kind regards from germany

probably brock because of size advantage , in an interview i heard jon jones say that frank mir took him down while they were in a ufc tour . i think the interview was with ariel halwani and the tour was in russia but not sure .

Jon Jones does quite well because he can use his size and strength against his opponents. I don't think he could stop takedowns from Lesnar or keep from getting pinned down.

Brock hands down

brock by ko or sub's if he get the takedown, jones by ko or UD if he stops the takedown and use his speed on lesnar.
