My conclusion really is that Naruto(as a series) doesn't have fights that are as one sided as DBZ, people aren't sooo amazing that they totally outclass others in the same way. If you have 2 amazing Shinobi,who are beyond jounin against another like Sasuke, you don't get a fight which is totally one-sided. It would be a close call. I personally think that just cause we didn't get to see Jiraiya against any Uchiha elite techiniques, doesn't mean he wouldn't know how to handle them. I don't think either of them would fall for a technique like that...not easily anyway. So I still believe the Sannin would win. With regards to Tsunade, I agree we haven't seen her do much other than suck but this doesn't mean she isn't a total badass. But hey, let's wait n see how she holds up against Madara. Might get some insight as to her potential.
