1. We can’t compare prime because Zoro hasn’t reached his yet.
I am only comparing Prime Oden to Current Zoro, I mean thats what you guys are saying right?That he already surpassed that Oden?
2. pre-1033 Zoro already replicated Prime Oden’s greatest feat, not to mention he did so with a huge disadvantage.
Visually yes, narratively no. Kaido made no mention of him being the ''monstruous samurai like Oden'' he foreshadowed nor did he even utter the name of Oden. As long as that doesn't happen then in Kaido's eyes Zoro is not comparable to Oden. Do you disagree?
3. Enma is more about its personality and the user’s fighting spirit rather than outright strength. Someone like Big Mom can’t ever wield Enma like Oden or Zoro, even though the argument can be made for Big Mom>Oden. Big Mom can die to Enma. See?
Its about a certain mindset and also endurance ( since Haki is related to your stamina for the most part) and it seems like Oden's stamina reserves far outweigh current Zoro as he can constantly output huge amounts of Haki while not being afraid of dying whereas Zoro was being worried not even 5 minutes in.
4. Using Enma’s behavior concerning each user, to scale each user’s strength against each other is fallible, because again, Enma has a personality in which it can choose to be tiresome or not.
I disagree mate, I can see where you are coming from but imo the intent of Zoro's wording this chapter and the last one where he was praising Odens ability to wield the sword are clear. Oden has not been reached yet.
And I think Zoro will reach his level or surpass it EOW, the arc isnt over ^^ and Zoro's growth rate has been rather impressive so far.
