I haven't used either of the coatings you mentioned but...I've had a couple rifles Cerakote'd and like it well enough.
If I were to do another one I would look closely at one of the Robar finishes. I have heard some good things about them, perhaps someone can chime in with some first hand experience.

Yeah, well, you know, that's just, like, your opinion, man.
