Best 5* to take to rank 4

Just looking for someone to make this decision for me, I like both champs equally and only have enough resources for one. I use them for story and alliance quests.

Both are unduped

Voodoo isn’t that great unduped. Duped is a different story, but T2A are more common that AG rn, so stealthy is your best bet.
