R3 6* Corvus, Cosmic Ghost Rider or Angela?

Which 6* cosmic champ should I rank 3 next? Corvus and CGR is unduped and Angela is duped with sig 20.

Trust me I love Angela's buff and Corvus is nice
But CGR is a cheat good
Though rank 2 is enough for him

I'd rank up that CGR and never use the others.

First rank up CGR after him take corvus if u can afterwards think about Angela

If Corvus was duped, I'd have gone with him.
