I can take one of these two champs to 5/50 next. Which one should it be?

This is my current questing team. I don't have the materials to take up Cap IW or Ghost Rider right now, but they're in line as soon as I do.

These are my current 5/50 champs. Hyp, Void, Killmonger is my AW attack team. Iceman is on AW def. Gwenpool was my first 5/50 and fills in where ever.

Feel free to share any thoughts on your vote.
