More comfortable. Full clockwise is harder rebound. As you turn the adjustment with the 2mm Allen wrench on the top of the strut there is a click about every 1/4 turn. Recommended setting in the rear is 9. By going from 6 to 9 there is a softer (more comfortable) ride at lower speeds. If you make it too soft you'll feel like you are floating at high speeds (not in a good way) especially if you make it too soft in the front axle.
