This is my second, smaller pedal board. As main board I use the Rockboard QUAD 4.2. The biggest advantage (and reason why I switched from PedalTrain to Rockboard) are the smaller gaps between the rails. Admitted, this is of more importance for pedal placement on bigger boards, but even on this tiny pedal board, it helps with cable management. I'm giving 4 stars to quality because mine came with a minor error in the loop tape. Little disappointed, but was an easy fix after all, and not noticeable anymore now.
