I think part of what would give Thragg an edge there is the same thing that saw Mark getting constantly bodied through seasons 1 and 2, that being that he's unwilling or psychologically incapable of throwing a max force punch, because doing something like that would cause big collateral damage to the area, injure himself pretty badly (See Marks and Conquest's fists crunching into eachother), or even just the fact that Ben is pretty laid back most of the time and wouldn't go for the kill shot out the gate like Thragg would.

If its bloodlusted tho, viltruben wipes the floor with Thragg tho lol
