Well the rooftop fight is telling a different story because Zoro was fast enough to bliz Kaido / have a clash and overhelm him when using Asura. He was faster enough to safe luffy from a close range attack from Big Mom motherly fire, he was fast enough to reach apoo that reacked to CP0 guys (which show to move very fast).
Zoro underwater was faster than a Odi, Zoro was faster than Kuma. Zoro can dodge beams
That is your opinion that Zoro cant keep up with snakeman or katakuri.
King need advcoc to get defeated a guy that has a better defense than the dragon scales which could handlemultiple boundman hits. Luffy stated that....all what he tried before chap 1009 didnt work....only adv coc.
As such King that has a better defense than Kaido dragon scale can handle too boundman hits and that was proof again and again. Nothing working until Zoro used advcoc. End of the story (it is not that hard to read this manga you know
)
Anyway you have your opinion that your boys are much stronger and I have mine which is saying the opposite.
