I don't know about any specific ones that are better than the rest. I usually just go to the one that is most convenient for me at the time.
One recommendation though is to not go to one where people are washing their work trucks, RVs, etc. I've found that since these trucks are usually dirtier than the typical mini-van found at all the other washes, the grim n debray stays on the brushes and gives a fine scratch to your car's paint (and I always spray down the brush before it touches my car).
