You may think that Cormega is a comparable talent but most would disagree. And AZ has one flow, it's really good but that doesn't make his flow better than Nas as can kill that same flow with no problem (see "Serious").
I like Cormega, he's more sincere than Nas and most would say he picks better beats. But he struggles to stay on beat and he's not nearly as nimble behind the mic.
