I don't know a lot about choppers other than the toy ones I play with but the risk of an unfortunate outcome due engine failure for me personally would be to high, each to their own I guess.
I've flown both and can categorically say that when all the noise stops you're safer in a helicopter in auto than a FW in a glide mate...(zero fwd speed/zero vertical Speed v 150km fwd speed zero vertical speed on TD) with practice you can do a precision auto in some very very tightspots as opposed to needing a runway size paddock.
