Yeah, I agree that he isn't on that level, but no one since Dangai Ichigo or Hogyoku Aizen has shown up since so I am not using them in terms of power levels.

Yes it evaporated moisture, but I feel with enough generation of water Kaien could counter it better them most other Bankai of Ice or Water type Zanpakutos. If Kaien hypothetical Bankai worked like a much stronger Shikai, (like most Bankai's) then going off his Shikai he could summons mass amounts of water, I would guess on Yamas level of fire generation or close to it (but that just guessing). Even if Yama kept evaporating it Kaien could keep summoning more and more.

Now to be fair tho Kaien Zanpakuto isn't likes Yamas, Kaien just has the ability to summon water not control it on the level Yama can with fire, thats why I said Yama is unique...now if you had another Soul reaper with a Zanpakuto that could control a element on that kind of level, bend it to your will if you may, then that person could fight him. But that all theory crafting so. :)
