I only use fast detail/quick detail type procucts of all brands. I can't really say which one I like best as I have tried so many and like'em all.
Mainly what I like is that, I don't wax anymore and my vehicles always look clean/polished after each washing. I use fast detail products after each washing/drying. Sometimes, I'll pass and just wash/dry.
Pick one, pick many! I usually buy from BigLot's or Ollie's to see what they have for about $3/bottle. Right now, I have in my stash, products from Meguiars, Mothers, Eagle 1, Rain-X, Nu-Finish and some off brands. Some, I only paid quick detail type products.
Depending on the color of your paint, you'll find the product that works best. Light colors(like mine) don't seem to matter on what brand/procuct I use. It's all in ones particular method of detailing that I find works best!
