Both seem to have Herculean strength. In a strength contest, I might say Jidanbou. In a counting contest, definitely Sado. In a real fight, it'd be a toughie. One is an elite shinigami(yet oddly enough, one would think Shinigami elite would be captains and not guardsmen) put in charge of guarding a gate. The other took out most of Squad 11(self proclaimed strongest division of the 13) in 2 minutes(so he claimed).
