5* Unawakened AA v 4* Awakened Domino

Hi, I'm pushing for Uncollected but I only have enough resource to upgrade one of these two. Who should I rank up?

P.S.
- This will be my first champion to get past 4/40 or 2/35.
- I have no Red Hulk of any rarity
- Other champs from the roster:

4/40
GR, Longshot (Awakened), Starky (Awakened), Stealthy, Warlock (Awakened), Iceman (Awakened), Havok

2/35
Void
