Let's not start downplaying Lucci now that he got bodied lmao. Lucci easily busted straight through Sentomaru's barrier, the same Sentomaru who successfully blocked Kizaru's attack. Sentomaru uses ACoA, the same technique Udon Luffy was dying to learn and Lucci blew through it like it was nothing.
Callback or not, Oda did not need to have Luffy match Lucci in G5. He could've done the callback in their base forms (which is what they originally occurred in back on EL) and then powered them up, but he didn't. So your answer to simply disregard the entire occurrence is a cop-out - feat-wise, Lucci was able to match G5 Luffy in a head-on clash of CoA. You can even see Luffy smiling as he feels the force of Lucci's punch before he gets sent flying.
Furthermore, Lucci received hype from Vegapunk for "astonishing speed" and later hype from Sentomaru, another high-tier who was straight up fodderised.
Which YC2 is shitstomping another high-tier in the same way Lucci bodied Sentomaru? Which YC2 or below is matching a powered up Yonko in a clash of CoA? It took Marco and Vista to stop Akainu alone - Lucci showed very good physical strength. Mihawk was babying Vista, incomparable to Luffy vs Lucci. Queen is the strongest YC2 villain and he could never replicate Lucci's feats lol.
Vs the seraphim, Lucci's non-awakened Shigan was paralleled with a CoC-less Kong Organ. His Rokougan was paralleled with a Kong Gun. That's a ridiculous feat because G4 is most definitely at least YC1 without ACoC, and Lucci wasn't even in his strongest form. He took a barrage of G5 attacks and looked totally fresh 2 minutes later. All the hype that Lucci received prior to this point indicates that he was a YC1 level opponent because anyone lower simply doesn't receive that kinda hype.
Zoro's just built different. He's a top-tier through and through.
