I use SKS Chromoplastic.
Those others are beautiful but not for me. On the bike that has fenders, it's covered with snow, road salt and/or mud a lot of the time. The fenders get beat on. I've had sticks blow into the spokes and wreck a fender. I wouldn't want to put on any fenders that I really cared much about whether they were dirty or got broken.
