I have used all three, WER, Scott's, and GPR. Each has a little different approach to achieving the same thing. That being said, I didn't find much, if any, difference in any of the dampers when I got them set up to my satisfaction. The WER does the job. When I set up the WER for me, I found I needed to use more adjustment than the Scott's to feel comfortable. But, that can be modified by the weight of oil used in the damper. Presently, I am using a GPR which I prefer because of the one big knob for adjusting on the fly. It is not any better than the others, it just fits my needs better.
