Nyriss is slightly superior to Anakin, slightly more to Vader, and to Dooku.
Scourge is around Anakin's level, somewhat above Vader and Dooku.
Exile is below any of them by an entire level.
Honestly, Exile falls to either before Nyriss/Scourge defeat their opponents 1 on 1, and then not even Nyriss can hope to win against Vader and Dooku at once. I don't see a setup where the strongest of team 1 (Nyriss) can take out anybody faster than Exile goes down against anyone from team 2.
