I'd put Shunsui and Unohana above Kisuke regardless of his war status though.
Yamamoto has more raw power and better techniques than the version that fought Yhwach a thousand years ago. Ryod had no memory of Yama's techniques. The only disabling feature was his pride + arm from FKT. The best version of Yama is Pre-Time Skip and IMO Kenny takes it. Too much raw power in his bankai.

Seeing the 5 war threats by Yhwach's list, this makes me thinking that EoS Kenpachi has surpassed EoS Yamamoto (which is weaker than his prime version who defeated Yhwach, growing old and became crippled).
But EoS Kenpachi vs Prime Yamamoto?
