Clipless are so much better, you can set the release tension quite low which makes getting your foot out really easy, and they are definately quicker than toe clips to put your foot in when you start. If you go for Shimano SPDs and a mtb shoe, you can walk without sounding like a tap dancer as the cleat does not touch the ground. I can't remember the last clipless moment I've had, but it was a long time ago, last time I went over the bars on a steep descent, I managed a tactical dismount and landed on my feet, it becomes automatic to unclip.
