Itachi. Without a doubt. Any Mangekyo technique one shots Tsunade, whether Tsukuyomi, Amaterasu or Susanoo. Does it with Oonoki as well. He can try to avoid eye contact, but will end immediately as fodder for Amaterasu. I guess Itachi could avoid Jinton with speed, given the fact that Madara fodderized Muu despite of having no counter against Jinton when alive and with MS only. Surely, Yata would take care of Jinton anyways.
For Oonoki, other Genjutsu are surely enough, too. Let him avoid eye contact and he will send out crows to distract him and same time catch him in a Genjutsu.
Even if you add Ei and Mei, they wouldn't beat Edo Itachi, as he can spamm Mangekyo techniques of Tsukuyomi's and Amaterasu's level and possesses perfect protection due to Susanoo, which wields two supernatural items that grant him ultimate offense and defense (even against Jinton). You would need Gaara, to do something against Susanoo.
