Doubt it.
Kin and gin brothers had access to kurama's chakra for the rest of their lives even though they only at some of it once.
It seems like it can infuse with a person and replenish almost like normal chakra
Well, sasori was MOSTLY lady chiyo. I'd say you're correct, but..... just to be a jerk...
If you count zetzu as a member of the akatsuki he has been taken down, like what... 50,000 times now? and that was most the 5 great shinobi nations... not just konoha :D
Nagato. His story would just be wicked awesome tbh, it would rival naruto right now, in my opinion.
If not then deidara would be my second option. There has to be a reason he got so strong so young.
Yea, pretty sure that's it. You kinda eliminated everyone else that could even remotely be considered top-teir.
Idk if you would count hidan still alive though, be he was pretty dangerous.
