This discussion, like all of this vs that, is almost pointless. UFC and such maches have rules. Some of these rules apply to striking. It DEPENDS on the situation and people involved. I seen street guy wop the hell out of people. One my instructors says the victory of the fight is the one whom can take a hit(s). Against my advice, I had a JJ friend that though he was so well in JJ, went to one of these "show and fight" matches. This brawling guy knock him out with one punch! From my years seeing, (and beeing in) bar fights and street fights, not even half wound up on the ground! I put this to you....if it started on your feet, and it gets to the ground, then you had less skills to maintain from keeping off the ground to begin with. Because the confrontation did not START on the ground.
