Which 4* hero to rank up (unawakened)

Comments

well both kinda need to be awakened to get their full abilities. By rank up do you mean 4/40? or taking them to 3/30?

I don't touch 4* until I awaken them

4/40

NEITHER

but if you MUST Ms.Marvel is poison immune and can take a hit better than Spider-Man.

Ms Marvel because of her poison immunity
