The Robbies also come into balance more easily than a 269, even if flown quite badly. The hughes is easy to fly, but not so easy to fly nicely. Personal impression.
Part of the case for piston is not just cost: Faster engine response is an added safety margin, helping to recover wrong inputs, especially helpful if a low RRPM exercise is poorly done or the wrong inputs made in a simulated engine failure, and using throttle to manipulate yaw is very direct when teaching torque reaction for yaw issues.
Having flown the Schweizer and Enstrom after getting my ppl in an R22, I must say that having to manipulate the throttle is a "no biggie" skill and certainly not worth the higher cost of training in those aircraft.
