Orochi > Jman > Tsunade
Sauske > Naurto > Sakura
Animal feat wise:
Slug > Snake > Frog/Toad
But isn't Sakura on her way? The only thing that holds her back is her heart, look at the clues. Sakura is resistance to genjutsu, even though her chakra control was restricted in part two, she still was resistant, and now her chakra control is greater and she has full control of it, + external chakra, so this means that her genjutsu resistance goes up, Madara showed that regen > the icky black fire stuff! Sakura possibly has the strength to break Susanoo, brute force was its weakness, and Naruto is more powerful than Sasuke bu I'm not really seeing how he beats him
Tsunade is though, in her battles she has always been either restricted or limited, so her full potential hasn't really been shown. Like oro and j man, she need a one on one fight, then we will see how bad ass she is,
