I don't think I have ever used a bad QD.
Some of the ones I have used with my comments.
4 Star UGE - Great stuff, but pricey. Probably my favorite QD.
Meguairs D51 Final Detail - From the Detailer line and discontinued. Cheap and good. May be loaded with silicone, but who cares.
Meguiars #34 Final Inspection - Under rated, good product at a good price.
Meguiar's A33 Quik Detailer - Decent and readily available.
Eagle One Wet Wipe & Shine - It was a gift and it seemed to work good.
In a class by itself!
Poorboy's Spray & Wipe - Not really a QD, but just as easy to use and it is not going to be a problem if you use it on a vehicle that probably was too dirty/dusty for a QD in the first place. Priced right and it has pretty much put my QDs on the shelf.
