With Amaun it was an enemy you feared. Everyone else was the typical big bad guy you'd expect to see. Amaun left us in the dark and constantly fearing for Korra where as Onolak, Zaheer, and Kuvira were basically the same kind of bad guy as the Fire Lord.

Onolak was lame.

Zaheer was much better.

And Kuvira was a bit more like Zuko's sister. (Drawing a blank)
But she was still repetitive.
