"Advanced" CoA/CoC is overrated anyway. It's false hype.
You literally can't even damage Kaido using traditional punches or slashes without barrier haki.
Internal destruction maybe overhyped, but then again Luffy explained Kaido had to dodge his internal destruction attacks because they were doing too much damage.
Advanced CoC allowed Luffy to clash with Kaido without fear and supression, creating sky splitting yonko clashes in base...
Adv CoC one shot Page One where the special OP laser failed to one shot Ulti and it also one shot Luffy both with Raime Hakke and Ragnarok.
Adv CoC user vs. non user can lead to a complete mismatch Like Roger vs Oden.
