The thing is pica is like cracker in my book (not in terms of power obviously there is difference) both showcased cool adarment Haki abilities (cracker bypassing gear 4th pics showing fbh) however both share one quality that makes them physically weakActually you can check some forums the chapter Zoro beat Pica, people started questioning if Luffy was even stronger than Zoro and were complaining Oda had taken it too far with Zoro's untouchable persona. Nobody including me expected Zoro to handle Pica the way he did, we all projected Pica being a hyped top executive would finally give Zoro his first challenge in the New World, but instead Zoro ended up making Pica look like a fodder.
They both hide behind things cracker with his souldiers pica with his statue pica obviously does not like to be hit which is why he ran into his statue zoro being obviously stronger then him it was smarter thing to do which is why I rank vergo above him (know this is kind of off topic) vergo is indeed a tank and his body litterally morphes into something huge because of how dense his Haki is that's why I rank vergo Haki > pica
Zoro needs someone who is actually willing to fight
I think oda is giving zoro weak opponents yes, however he is showcasing what it takes to beat zoro or at least change entire difficulty of the fight and that is mainly speed (with the monk girl and pica and even the yeti guys with that swift movement )
Both zoro and sanji will have their moments but they both need power ups but even with portrayal and being best fighters of Luffy crew both are lack luster as **** compared to gear 4th
Also to the guy who said aura and hells mementoes are not comparable ??? How both are ultimate attacks made by the two chars sure sanji showed his later then zoro but both are attacks however I believe both will get their modes in their respective forms
So a flaming burning sanji with Haki
And an asura zoro who basically (I believe it's with his aura) has multiple arms to basically block and attack everything in sight
I cannot wait to see asura again that and the kuma thing and the Mohawk thing in the beginning have been my favorite moments with zoro
