Clipless, Power Grips, toe clips and straps, I've used 'em all. My conclusion has been that I'm happiest either with clipless or plain old flat pedals. I'm not a fan of any of the devices that put a strap or clip over the top of your shoes. The very large majority of my riding time and mileage is with clipless pedals, but the bike I do most of my commuting on has cheap resin plastic pedals. I don't find myself missing the benefits of clipless pedals on that bike. Though the commuting bike right now is a fairly upright hybrid and my ride distance is short, I first tried using flat pedals without clips when my commuter bike was a drop bar touring bike. I liked them just fine on that bike, too. For a bike I'm going to ride in street clothes, being able to just hop on and start pedaling is super valuable to me. For me, in those circumstances, I don't think attaching my feet to the pedals has any real benefits, just aggravation.
