Question: is jiraiya the strongest sannin?
Answer: Orochimaru, in all aspects of fighting is by far the strongest Sannin. This, is not even a close comparison. Orochimaru was on a completely different level then any of the Sannin, and without arms was more then enough to take on Jiraiya and Tsunade. ... So here we can safely say that Jiraiya is stronger than Orochimaru.
