This year I have retired my old strike master gas auger.  It was an old two blade auger that cut through miles upon miles of ice in the last twenty plus years.  I have replaced it with a nils auger powered by a milwaukee fuel cordless drill. The nils auger is in a league by itself when compared to a k drill or even an ion battery drill. I feel the only thing on the market that competes with this setup is the strike master forty volt this is only my opinion and it does not take consideration when an extension in needed in very thick ice.   The niles does not pull hard and breakthrough at the bottom of the hole is almost undetectable.  This auger does not kick back at all.
