I find them more secure and easy to use. Also no clip = more toe clearance. Go with good ones like YNots which are thicker than some of the cheaper brands as they hold open better and make getting your foot in easier. They are comparable to double straps and clips as far as how locked in your foot feels. The only negative is that they don't look as classic as straps and clips if that matters to you. Personally I prefer the wider, cheaper, and lighter BMX style platfom pedals they are are usually paired with to even something like GR-9s for use with street shoes.
