I used Planet Bike fenders on my commuter down in Boston. No complaints, other than the forward mounting clip for the rear fender at the bottom bracket did not come even close to fitting the chainstay bridge on my old c-dale mtn frame. Zip tie fixed that.

Currently running VO smooth aluminum fenders on my main commuter. I like them better than the PB fenders. Longer, so more coverage, especially up front -- dry feet are good... I like the fact that you drill your own mounting holes to fit your own bike. Hint: swap out any nuts they send with the mounting hardware for nylock nuts, or apply threadlocker. 1000 mi on the fenders, one bent from loading it in a car, and I bent it back; once, some hardware came loose on the road and I had to kludge a fix (zip tie) until I could get a new nut for it; I just went over all mounting points during a complete bike overhaul to take care of some rattles a year later. Bike is silent now, and still looking way classy with the metal fenders. ...which don't cost as much as some plastic ones...

I'm sold on metal fenders, will probably use them on any commuting bike I put together.
