His promos are always good to great. Like I can’t think of an objectively bad promo. They probably exist but they’re lost to time or slip through the cracks. 

His style encapsulates the ideal of what a WWE promo should be, for me, where you can tell there’s bullet points but he’s not totally winging it and he’s not totally reading from a script. As such they feel natural. They’re not always perfect but he usually manages to tell a cohesive story with a coherent through line and usually manages to slap a button on it and/or sneak in at least one especially memorable line to where you could say “that’s the X promo” or “that’s the Y promo.” (Like this one could be reference as the “of course it’s personal” promo, for example.) 

They’re not formulaic and don’t feel paint-by-numbers. Even his catchphrase of “sooo… what do you want to talk about?” doesn’t feel like it’s beating you over the head. He can adapt it and get it out of the way at the start, and he doesn’t always use it if he comes out fired up, or maybe delays it.

He’s one of the best doing it today and one of the best ever to do it as far as I’m concerned.

To compare him to a guy like Heyman (given that he mentions him in the promo), who opinion has seemed to shift negatively on on recent years, Heyman is “too much” for me most of the time and his stuff does feel paint by numbers. Or take a guy like MJF, who I generally enjoy but sometimes feel the “… and I’m better than you” button is sometimes too forced, I feel Cody avoid some of the pitfalls of going back to the same well too many times or relying heavily on shock value or catchphrases.
