Last year was first time I tried this type of product. I picked up a gallon of QEW, then orders 3 galllons. I don't use it all the time in my business but I use it often enough. A while back I tried a 32oz bottle of ONR. Ignoring the smell I tried it a couple times and didn't like it. The bottle sat around for a while and eventually I used it up. I just couldn't toss it out. As we neared winter I decided to try DP4in1. Winter was when I used the most QEW last year and before I orders a few gallons, I wanted to try DP out. Certainly smells better the ONR. I've tried it out a few times and still prefer QEW. I keep reading others reviews on the products and seems like most prefer one of the others over QEW.
Now for me QEW seems to glide when I'm using it. The dirt seems to release from the paint and whatever I'm using to wash with better too. Wondering if water hardness affects things. I think our water is moderately soft 4-6 grains. Whichever product I used though I couldn't tell any difference by looking at the car afterwards. All three did the job, just QEW currently is my choice.
