There are a lot of shinobis with similar strengths so I dont think you can really make a "top -10" per se.
I would say
Hashirama, EMS Madara
Naruto, Sasuke(no godly power ups)
Itachi, Nagato, Minato
Tobirama, Hiruzen, Obito, Kabuto, Jiraiya,
Orochimaru, 3rd Raikage, Bee, Kisame
Kakashi, Danzo, Oonoki, Mei, Ay, Muu, Shisui(my guess), Tsunade, Gaara, Deidara, other akatsuki members i missed
Yamato, Neji, Gai etc.
rest fodders
You cant have a top 10 without Nagato, Itachi, Minato, but you cant have a top 10 without kabuto or obito either. Its though so you cant just pick one and leave the other out. There are too many characters with similar power levels so I cant say this over that. There are too many powerful shinobis
