I think it depends on the usage
Hashi is godly in 3v3 PvE (including ranked) and damage races(fox/coin trial)
Tendo is good in any 3v3
9-tail naruto and Ay are more for 1v1, Ay being on par with 3* I'd say, 4* is probably stronger.

Overall, I'd rather 9-tail naruto higher because there are more 1v1 PvP stuff in the game than... well... other stuff so it probably gets more uses.
