This is good. But it's still only one example.
Most people don't think Sanji is very strong or worthy of being the captain.
Meanwhile Zoro gets multiple moments like that
This isn't really a fair statement but going to assume you just phrased it incorrectly.
Is the bolded bit in reference to only Absalom having commented on this? Or are you saying that there are examples of people saying Sanji isn't very strong, invalidating abasalom's statement? cause the way you phrased it sounds like the latter.
Zoro getting multiple moments is more power to him, but it really has nothing to do with this thread and overarching topic at hand imo.
This isn't a Zoro/Sanji dick measuring contest. The question is whether or not Sanji strength has ever been considered unordinary and beyond that of a subordinate and the answer is yes.
If we really have to make this a "Zoro is much better or special bcoz he has had more references" then my argument to that will be that Zoro simply gets ways more fight focus and combat spotlight than Sanji does hence the difference. To give a real world example, the more you swipe on a dating app, the more matches you will get. Which imo is fair, given that fighting isn't really all Sanji does. In additional to his exceptional fighting prowess, Sanji is also an exceptional cook and also gets focus on that so it balances out. Moreover the way Oda writes both Zoro and Sanji is inherently different. For one, Sanji doesn't have the same supernova dynamic that Zoro has with Luffy. He also prefers to keep Sanji low-key and have him do shit in the background as opposed to being smack in the middle of conflict.
Basically, Sanji is not Zoro but that doesn't really restrict him from also being an outlier in Luffy's crew which shouldn't really be that much of surprise objectively speaking given Luffy is going to become the Pirate King 💀
