About summonings buying time for Jiraiya's SM. As I remember, those frogs are quite fast and agile despite their size, so I think it won't be so easy for Tsunade to actually hit them.

Also we should keep in mind that whole sannin being a three-way deadlock thing. Which basically goes Tsunade>Oro, Oro>Jiraiya AND Jiraiya>Tsunade (something you can check here: http://naruto.wikia.com/wiki/Sannin#Trivia)

Conclusion: I'd bet my money on Jiraiya, and by gambling skills a far beyond Tsunade's.
