No , Zoro's goal is pure strength , Luffy wants Strength to protect his friends , that simple logic makes it obvious Zoro >=Luffy
Well who is his friend? Remember what Luffys aid in EL against blueno, he has friends weaker than him that needs his protection and appears Zoro image too, so him is weaker than Luffy.
Look to Luffy's opponent's.
BM or Shanks(Elbaf).
Marine(Akainu).
WG(Imu or One of the Goroseis).
Blackbeard.
Future Zoro opponents.
Beckman or Katakuri(Elbaf).
Fujitora.
Ghandi Gorosei.
Shyriuu.
Mihawk.
Blackbeard will be a PKlevel guy, on Roger and WB's level.
Akainu is the weakest of them but is a Top tiers notheless.
Goroseis is hyped to be ultimate Villains and Imu too.
Luffy i already facing Top tiers in the next arc he will defeated one in 1v1.
