SM Kabuto already has shown that without Sasuke+edo tensei, Itachi would've been toast in minutes.
SM Naruto spanked Kurama. Not to mention, his Senpou Fuuton: Rasenshurikens are huge now. Sasuke's Susano'o would be obliterated unless it's Perfect Susano'o, at that point, we don't know what it can really tank.
SM Jiraiya has ma and pa for backup and took on Pain without knowledge. He could've defeated a Rinnegan user if he knew Nagato's secret. And for the record, Nagato himself would've probably been an easier match for Jiraiya since he's just one body and can be pwnd in frog kata and blind spots a lot easier, especially against a sage. Who has 2 sages on his shoulders.
SM Minato only appeared once and got pwd. But that's because.....oh idk.....he was going up against a god jinchuuriki. The only being in the Naruto universe to harm Minato were 10-tailed jins. I don't consider that as a failure for someone who has no kekkei genkai or tailed beast during the confrontation(against Madara). Only SM. He pwnd MS Obito in less than a minute, mostly due to Obito monologuing. I don't even wanna know what would've happened if he had SM active the entire time. And Rinnegan Obito is only apparent if he has the 6 jinchuuriki at his side. If not, then he's still just MS Obito.
IMO, sages win.
-Things for sages to watch for: Sasuke's Perfect Susano'o, Obito's space/time, Itachi's Totsuka blind spot counters, Pain's absorbing, Shinra Tensei and Chibaku Tensei.
-Things for doujutsu users to watch for: Combined frog kata combo's, Minato's FTG+sensing, Naruto's massive Rasenshurikens, Ultimate Rasengan barrages, Kabuto's White Rage, Kabuto and Jiraiya's sound genjutsu.
