Moving a blackhole is a much more specific case and is hard to gauge tbh. You can see that I've already said (in earlier pages) Vaylin isn't superior to anyone in the force who doesn't have her TK feats. If this was someone like Dooku fighting Vayling for example, I'd side them despite Vaylin's superior showings in this area. Malak on the other hand has almost nothing going for him, and your main argument is indeed Senya = featless > Vaylin.
