A fixed wing aircraft that loses power is automatically a glider, and a helicopter that loses power is automatically autorotating, what you’re talking about is successfully walking away from the resulting landing. Well, assuming loss of all engine power without the possibility of restart or the contribution of any secondary or emergency power systems, where the pilot’s ability to balance lift with gravity is the only concern, then I’d definitely take my chances in an autorotating commercial helicopter over a gliding commercial jet of the same weight and passenger count and starting at the same height and potential energy state over the same city any day.
