Legendary sannins win here....
Jir, Oro and Tsu show team work and excellent collaboration with each other when they are supposed to be team...and they got loads of XP doing that...
Nar and Sas would show some team work if they are supposed to be team but sakura would be a pain in ****.....
+
Oro's+Jir's intelligence > Sas's + Nar's
that says it all......
At this point, I'd say Naruto, Sasuke, and Sakura would be able to defeat Jiriaya, Orochimaru, and Tsunade. It's not simple to say because the sannin's battle experience could certainly play a part and also the fact that other than Sasuke wanting to kill Orochimaru the others get along.
i know that jiraya have a counter jutsu against amersatu.Remember in part 1 of naruto when sasuke was looking for naruto and bound up to itachi and kisame and naruto.Jiraya came after and save them,Itachi and kisame escape by using amarsatsu at the wall,then jiraya take a sample of the flame to research it.Do u remember?
