I have been shooting a Trophy Taker XFC rest that is a cable driven version of the Smackdown. Killed three deer with it this fall and has proven quiet and reliable.
I've had 2 of the QAD rests on my last bow and new bow I just got his this year. Never had an issue with either in 4 years. Not sure about the other brand but don't have a single bad thing to say about QAD.
