Neither Naruto or Sasuke have sealing techs. So they will never defeat Oro's Edo's.
Tsunade will own Sakura leaving the team without a medical ninja besides the fact that sakura isn't supposed to fight as per Tsunade's rules and she's supposed to be the last to die but she would be first. Oro and edo's could stall Naruto while The third hokage and Tsunade Byakougou double team Sasuke defeating him. Both situations end the same way so Jiraiya would curb stomp kakashi. Kakashi just doesn't have enough chakra and he has the problem of kamui working on moving targets. I assume they would bring out their summons Monkey King Emma would destroy the dogs, Gamabunta and the other toads would be more loyal to Jiraiya, Manda and the snakes have no reason to help sasuke, and katsuya betraying Tsunade? I don't think so. Which leaves The third hokage, Oro, Edos, Tsunade, Jiraiya, and their respective summons against naruto. Simply because there is no way around the edo's naruto would lose
Even without the masters present Sakura would be terminated and then two sannin would destroy sasuke. If you're telling me Sasuke can take Jiraiya and Tsunade at the same time you deserve to epically facepalm yourself. SM Jiraiya is very impressive, Tsunade would serve as support breaking susanoo and healing jiraiya, perhaps even joining the fray herself. They are both fast enough to escape ameratsu. Jiraiya won't be caught under genjutsu as per Ma and Pa toad, Tsunade won't become caught because the other way to stop genjutsu is to stop your own flow of chakra and because she has such excellent control of her own chakra she can do this. And both have been around long enough to not look an Uchiha in the eyes. Naruto is also genjutsu proof due to Kurama so Ma and Pa will not be singing to him. However, I doubt he can single handed take all three sannins, their summons, and oro's edo's all at once.
am going with the sannin
