I go with Jean Grey fuerza fénix

Obviously Jean Grey, Atom Even can't do everything that Jean Grey can do. Especially with the fact that she has the Phoenix Force.

Phoenix is so much more powerful

Imma also go with Jean Grey

Definitely Jean ❌

Phoenix Force, really? You couldn't do more with Atom Eve? It's that obvious.

^ To be fair you can still essentially do whatever you want and control reality, you just don't have to worry about a crazy firebird possessing you and turning into dark Phoenix
