Yeah, and we will see how Kizaru will be after this chapter. Even though, if you are trying to imply that Kaido is a much better tank and much more physical resistant, you don't have to: I totally agree lol.
In fact, I think no one is a better tank than Kaido period, not even Roger, Garp or WB since they did not have a Mythical zoan.
For now, we are comparing the 1045: Kaido received a weaker hit and was sent to the floor white-eyed (and as I said he is exceptional even for top tiers in that regard); Kizau received a stronger version, was midair and was sent flying. I honestly don't see the problem for Kizaru here. Instead, point for him in some way for having exhausted the G5.
