1.Current Obito Uchiha
2.Nagato/Pein
3.itachi Uchiha
I don't know about the rest honestly, Zetsu is the weakest, Second weakest is Hidan, If konan actually does need prep time to do that thing she did to Obito then she is the third weakest. I consider Deidara above Sasori by a stretch, Sasori may be dangerous than Deidara as Deidara stated but not above all stronger than him by the feats i saw from Sasori fight from Sakura and Chiyo and Deidara fighf from sasuke, I consider Kakuzu to be above above both of them because of his non penetrable iron skin (except lighting element) and his large scale AOE elemental attacks, he can definitely tank anything Sasori can throw at him. Not sure about third Kazekage which can definitly give Kakuzu a hard time, but immortality with large Aoe attacks plus Iron skin can assure he the victory. I saw him tanking a explosion from a Explosive tag Kunai so he can probably tank anything Deidara can throw at him with iron Skin. C4 mini bombs can work if you breath in them , now unless somebody can explain how a iron stone Object can breath then C4 Mini Bombs won't past through Iron Skin. And lastly I consider Kisame to be above Kakuzu because he can asborb anything Kakuzu can throw at him. So to continue ony list, its
