I have a feeling that the answer to this one is that it really doesn’t matter.
I have three 5* champs right now, Daredevil, Jessica Jones and Thor. I have extra covers for Archangel and Ghost Rider saved and I’m just curious if I am overlooking any reason to champ one before the other.
Well Ghost Rider is the better of the two I think however, from a power color distribution, you might always be using Thor’s green power and that is Ghost Rider’s best if I remember. If I had to choose, probably Archangel since you do not have an active blue AP user but as you noted, it doesn’t really matter with those other 3 champed. I would save the iso myself if you have any other 5* getting close to 13 covers lol.
I’d go with Archangel. Daredevil and Thor, thanks to their 50% health “next trick,” are pieces you’ll want to use a little longer at a stretch. Jessica needs to be benched more frequently, and Archangel is a better color match with DD and Thor than Ghost Rider is.
In a post-gambit world, both are OK, but in my view Angel is a little more OK (active blue, good counter against some future flying 5*, etc.). If you’re mostly post-ISO where champing another 5* doesn’t concern you if you get lucky enough to cover, then I would go that way; otherwise I’d just save the covers and maybe you’ll be in a different place the next time it comes up.
I think I have decided on Archangel because of an active blue and a stun. He actually seems ok, just expensive powers.
I really like GR but I don’t have a strong Thor. So for I think archangel is better.
