I love the clipless on my road bike, but on my commuter, it's platforms all the way. I made the switch after discovering that in an emergency, my disc brakes can stop me quicker than I can unclip. Slamming on the brakes to avoid a car turning in front of you doesn't do much good if you tip over into the traffic coming from behind you.
