I also have the Planet Bike Cascadias and they are just perfect to keep the water and grime off me and the bike. I found the SKS and PB to be essentially the same. They fit well, are cheap, and sturdy. If you want the best, maybe those berthoud or something from Velo Orange would be of higher quality but they would not shed water any better. Any fender will shed water. I chose the PB for an inexpensive solution on a commuter that will see salt and grime in the winter time. I did not want anything really fancy, just plain plastic fenders with stainless steel hardware that will do the job and last a long time.
