If these two Legendary Sannin fought each other, who do you think would win? They seem equally matched to me, but I think Tsunade would win because she is strong and can heal herself, but Jiraiya knows lots of Jutsu.

yup it would be a close battle but i think jiraiya would win because most of Tsunade attacks are close range and with Jiraiya porcupine hair technique thingie (i forget watits called) he could defend well against them and also if jiraiya is on gamabunta how is she suppose to reach him? and if she did jiraiya would have a good amount of time to dodge. Personally i think Tsunades slug sucks and that gamabunta could kik her ass if it came down to it. About Tsunades healing, i think she needs preparation time in order to heal herself fully so Jiraiya could attack her easily during that time.

Tsunade is strong but she is more like an healer and not what people would call a damage dealer.
Jiraya can summon more than just Gamabunta I think I saw him once summoning a frog with a big shield and once one in an armor so it could be like a whole (frog)troop against her

Yes, but Tsuade is physicly stronger than Jiraiya, by alot and she can summon too. Jiraiya has lots of Jutsu, but is a pervert. Tsuade could do a "sexy jutsu" and Jiraiya would be defenceless.

Jiraiya kerpwns her. She might be physically stronger but has way more jutsu. Ok tsunade has summon, but its no match for gama. This is just liked an over-powered naruto v sakura.
