Honest question: How on earth can anyone come to the conclusion that Zoro fared better?
At first he attacked Kaido's neck together with Killer, which only made Kaido chuckle.
Then he tried one big hitting move, but Kaido easily dodged it.
Now we come to his biggest achievement: He blocked that one combined attack from BM and Kaido for a second. That was a great moment for him, yes, we have to be fair.
But we go on: His by far strongest move (Asura) was a nice blindside hit, but it really didn't bother Kaido that much either. He was totally fine and fighting the very next chapter.
Those were all of Zoro's scenes against Kaido.
After that Zoro was completely out of the picture until he got roids this chapter btw.
So where on earth should that be "thousands of times better" than Luffy, who actually stood his ground in a real 1-vs-1 battle for quite some time and got several clear hits in, which also made Kaido cough up blood multiple times?
And now once again, since you only came around with whataboutism (like I predicted) and had no answer to the original question:
If Zoro was indeed stronger than Luffy, why is it that everyone always puts everything on Luffy's shoulder each arc (he is the one that has to defeat the by far strongest enemies each arc), while Zoro always gets the much weaker opponents and still has to give it all?
A better question is how can anyone say that he didnt after seeing it with their own eyes? Only trolls I guess.
Zoro's first attack on Kaido made him chuckle? Do you remember what Luffy's first attack did to Kaido back in Kuri? Nothing.
Kaido didnt dodge - Zoro "missed". Doesnt matter which form of Kaido you pick, Zoro is shown as superior.
If it is base form, Zoro is the one who ends up hitting Kaido while Kaido fails to hit Zoro.
If it is dragon form, it is Zoro who bests Kaido in dragon twisters and cuts him clean, not the other way around.
If it is hybrid form, Zoro is the one who bests Kaido and rips his chest open.
As you see, regardless of the form, the portrayal favors Zoro over Kaido, every single time.
Now, let us see the portrayal between 3 Kaido's forms and Luffy:
In Kuri he KOes him, on rooftop he almost KOes him.
In dragon form, he ends up eating him.
In hybrid form, he KOes him two times... As you can see, regardless of the form, Kaido gets the best of Luffy.
I can clearly tell that you are butthurt about it the moment you call Asura a blindside hit while Zoro literally called Kaido out into CQC.
You were cool and chill before, because you probably dismissed all we said as "nonsense of the Zoro fanboys" but from the moment our nonsense got backed up by Oda himself, you became butthurt and are bitter ever since. A changed man so to say. I thought OEKaneki would be the most butthurt one but you are beating him easily, probably because he still is dismissing it and living in fantasy but his denial has an expiry date too.
What did Luffy do? Where is that 1vs1? The off paneled thing? lol even Yamato can last in off panel, longer than Luffy btw.
He made him bleed? An amazing achievement, on par with Scabbards, actually worse since they didnt skip the hard exterior to make him bleed.
Why is it that Zoro is the one who is facing island buster from not one but two Emperors and protecting his "stronger" captain instead of the "stronger" captain protecting the "weak" Zoro? Do you realize that nobody ever will have such a feat? And Zoro is the only one who could have done something about it, not your boy Luffy.
Considering how much of a big deal the story made giving Kaido a scar, what Asura did to Kaido is far more than anyone else in the world did, including Luffy, Shanks and Big Mom who recently fought Kaido. What Asura did to him actually is the biggest achievement by far, not only did it give his body 2nd ever permanent scar but it also made him show first signs of exhaustion in the whole battle. Zoro did with 3 hits more than what Luffy did with, give or take, 53 hits. Can you even grasp how big of a difference among them there is?
I already answered your question, if Luffy was better than Zoro, he would perform better than Zoro against Kaido and yet, it is Zoro who protects and carries Luffy's ass, not the other way around. Another sign of butthurtness is saying that Zoro gives his all while he actually mid to high diffs his opponents while Luffy almost dies trying... Zoro neg diffed Hody while Luffy almost died, literally...
Why is Zoro tasked with pushing the Birdcage instead of going to low diff Doflamingo?
You no longer can dismiss it as nonsense because Zoro's feats, both offensive(scaring Kaido) and defensive(facing Hakai) are never going to be surpassed by Luffy. He simply doesnt play in Zoro's league, which is in line with what I was saying, Zoro is supposed to be the strongest character ever, not Luffy and it is time to accept that. Literally ask yourself what Zoro's purpose is lol and you will realize it.
