Adele is actually quite nice, especially once awakening hits in a month. Her passive gives everyone 10% more max health just by having her in the team. If anything she is an incredible addition once we get hard hitting bosses that love to oneshot things. I'd love to get her but i am not going to spend on a spotlight with so many units that i already have...

That said though, yes some units will help more, but not all blacks are that amazing at helping in the start. Chances are that he will get Sybilla or Liana, and neither will help him tremendously until the later maps. Rather just think long term with Adele in that case.
