I think there should be absolutely no doubt that clipless is better in general. You will know how easy it is to pull up on the pedals. Straps are good only when tightened, and in order to tighten them well you have to pull up on the loose end after you put your shoes inside, which makes them a hassle. The downside of clipless is that you have to get special shoes. I have a pair of shimanos I got couple of weeks ago from REI. They are black with mesh on top. I wear them all the time like regular shoes, super comfortable and low profile.
