I have 7 or 8 different brands including Griots, P21S, Absorber, Water Bandit, Baja-Sol, Meguiars, and some others. I like the Water Bandit the best of all of them. It has the nicest texture and feel and is less "grippy and sticky" when pulled against a surface. (I don't use it that way but that is one facet of the test I did) It also absorbs the most water per square inch. I did a comprehensive test last year but don't have access to the stats right now. It has a "waffle" texture where most of the others are smooth.
They all rate pretty close and I don't dislike any of them but the WB was just a step ahead.:xyxthumbs
