If you are talking about a fight when they are at their prime it would be Jiraiya and Naruto's victory.
This is because Naruto would have his new form and for this to be a fari fight we will have to see the power of sasuke's new eyes.
Also Itachi once said to Kisame that Jiraiya would beat them both and for them to kill him they would have to die as well.
It would basically be the power of two mangekyou sharingan(not eternal) versus: a legendary sannin, the jinchuuriki of the nine-tails (full control) and two toad sages.
If you look at techniques, our 2 Uchiha have: fire ball jutsu, chidori and chidori based moves, kirin, sharingan(mangekyou),amaterasu, susanoo and a lot of genjutsu.
The sages have: Rasengans, Rasenshuriken, Shadow clones, Toad summonings, Sage mode, Jinchuriki form and Earth, Fire and Wind natures.
It would be a cool fight but there is a lot of power on the Sage side.
