The writing is far worse, like how do I put this?
Imagine if Kaido was not only 100% the strongest physical Top Tier in the verse but also had a devil fruit ability that would allow him to pretty much take on every other Top Tier single handedly. An ability so broken, that no other hax abilities can work on or even touch him. Not even in-verse reality warpers can do anything to him.
Not only that but he has CoO so good that he can simultaneously see every single possible future at once with no downsides and the aforementioned devil fruit ability allows to reach into the future and manipulate events before they even happen.
Not only that but Kaido also has a bunch of insanely strong subordinates with absolutely bullshit abilities that break the verse. For example, one of his lesser subordinates is just a straight up reality warper that can imagine anything and will it into existence.
Not only that but Kaido's devil fruit allows him to absorb and take every single other ability of all of his bat-shit insane subordinates upon their demise, including the reality warper.
Not only that but Kaido legit found the One Piece and is now just straight up God because sure, why not?
Now, imagine that this version of Kaido (who has either personally beaten every other Top Tier or has had his subordinates stall all other Top Tiers) is defeated because Usopp shot a sea stone bullet at him (which his Future Sight should have seen from a mile away) and this allows Luffy to one shot with a nameless attack.
Then instead of seeing the aftermath of any of this, we are immediately catapulted about 10 years into the future when everyone is retired with zero context or reason.
That is how Wano would end if Kubo was writing it.
