Zoro is a physical monster, I would not put a cent on Asura Zoro being less powerful than even Boundman Luffy, or at least Snakeman, under equalized levels of CoA I mean.
Besides, Luffy's TS training is not that different than anything Zoro undertook through all of his life, it's just it was particularly efficient... but Zoro's training(s) was no joke either.
About FS... Luffy managed to break through Katakuri's FS thanks to his Snakeman speed... I'm fairly confident Zoro could attain the same if we consider that Luffy's level of mastery of the FS is not comparable yet. So it's not that much of a mastodonic issue for Zoro to deal with if things stand this way.
Regardless, Zoro is also an endurance monster, Luffy lacks a bit in that aspect.
