Alright Sasuke, Naruto and Sakura wins, even though it will not be as easy as people think...
Sasuke defeated Orochimaru when Oro was greatly weakenend, Orochimaru full power with Edo, would be able to do a lot for example he could summon some kage level shinobi to his side.
Naruto will defeat Jiraiya, since Naruto is able to use Kurama to pretty much full potential, if naruto doesn't have Kurama, then Jiraiya would win over naruto without Kurama.
Tsunade we all know is better than current Sakura.
I'm a huge fan of jiraiya and well but in the end Sasuke, NAruto and Sakura wins, but not easily Sakura will lose, Sasuke and Naruto will have a hard time fighting.
Naruto will be irritated over his sensei perverted ways so he will be annoyed lol,
Sasuke well current sasuke is better than Orochimaru but it won't be easy to handle him since he got Edo and he can use Hydra and he can easily defend himself.
The Sannin are great but i have to go with Naruto and Sasuke and Sakura, only because of Naruto Kurama combination and Sasuke's current incredible skills.
