The main thing that made her my favorite over Semirhage or Lanfear was that what she said was often at odds with what she does.

She said that if openly confronted by a more powerful opponent, she would flee - but when confronted by two opponents that combined were a very dangerous threat (Cyndane and Moghedien) she took tactical action and aggressively attacked - in fact her tactics were better than Ishamael or Lanfear's in that scene. No gloating, no monologues, just a manipulation of battlefield conditions, a dodge, and an attack with her strongest weave.
