1- When the strawhats were about to be captured in the Ryugu palace, it's Zoro who took control of the operation, making them hostage and using them to make requests favourising their leave of the island. It only turned bad because he didn't expect Hodi and Decken's gang to comeAre you serious? tbh i think this man is trolling.
You find way more Zoro's then you do Sanji's lmao. Not to mention Jiraiya and Kakashi are nothing like Sanji. Sanji is actually an unique character whereas you can find Zoro in every single Shonen manga out there.
The only thing Sanji, Jiraiya and Kakashi have in common is that they're pervs. Sanji's personality is nothing like theirs+Sanji isn't your ordinary shonen perv. He actually gets b*tches U_U
Zoro is just the cliche grumpy badass character. Although Zoro is one of my favs im not biased, i admit Oda has done some stupid shit with Zoro's character. Post-TS all he does is spend 90% of an arc doing something useless and then 10% fighting. Pre-skip he had a much bigger role then just the "badass" fighter who shows up at the last minute to whoop ass.
Pre-skip Zoro was somewhat unique. Post-skip he's turned into just another wolverine/Kenpachi.
2- When Luffy lost to Caesar and himself got subdued by Yeti Cool brothers, while everyone in the crew was taking things lightly, Zoro didn't(for a reason). If the strawhats crew continued to be so careless, the group will achieve nothing in the new world and Zoro understood that and because of this he reprehended Luffy(and the crew) about their doings
3- He showed change in character with Tashigi in Punk Hazard. Before he was avoiding her at all cost, but now he can speak to her face to face accepting her not as Kuina's double anymore and even helped her when she couldn't move on her own to escape the Smile's gas
He may not have been the most developed strawhat, but i don't see how Zoro had no development post-skip
