I don't use clips, and clipless for extra performance, they just help me keep my foot on the sweet spot of the pedal without any thought or effort which reduces fatigue. It also eliminates pedal slip in the wet on hills without tearing up the soles of some of my shoes like pins do.
I'm not the most graceful person in the world, yet I've never had an incident using clips with loose straps, or Shimano Click-r clipless pedals.
