What's this weak reply 
Luffy learned Ad.CoC from Rayleigh-Kaido experiences.
Zolo couldn't learn Ad.CoC from Mihawk-Kaido experiences.
Mihawk also didn't show CoO, and didn't show CoC.
So you can only run your mouth about CoA, which is Mihawk and Zolo's Haki speciality. Zolo's CoC is lower level for sure.
Why Mihawk's CoC would be superior to Zolo's?

The fact he got taught haki AT ALL destroys your point.
