I suppose that does muddies the waters in that fight, but I still stand by my previous statement. Orochimaru > TsunadeThe gimmick in that Sannin battle was that all three were heavily handicapped.
Jiraiya had been drugged, Tsunade was drunk & out of shape and Orochimaru didn't have his arms. This is the reason Kabuto as back-up was actually a big factor and allowed him to fight on par.
