Azazel also said this:

“Ah, that was the [Juggernaut Drive].”

“Is it something above even the Balance Breaker?”

“No, there exists nothing above Balance Breaker. The ultimate and final form of Sacred Gears is the Balance Breaker. However, there are several things inside Sacred Gear that have a magical being sealed in them. A peculiar restraint is applied on those ones. Your Boosted Gear and Vali’s Divine Dividing are examples of that.”

As seen here, it is clear that as far as Azazel is concerned, logically, raw power does not make an ability necessarily better (Juggernaut Drive is clearly "stronger" than Balance Breaker, but Azazel specifically said it's not above it even with that). CxC rivals Juggernaut Drive because it is safe to use and is stronger than the normal Balance Breaker. Taking these advantages into account, it rivals Juggernaut Drive but still does not have the same raw power. It doesn't need it to be something on its level. If CxC potentially had the raw power of Juggernaut Drive on HD-class it wouldn't be something that rivals it, it would be strictly better, and that's not what Azazel said. And CxC and Triaina being Ddraig's original aura does not mean they use the full extent of it or even can use the full extent of it.
