John:

I have both though the (large) majority of my miles are clipless. You won't confuse the two. The absence/presence of the clip pushing into the top of your foot is a constant reminder of what you're pushing. For comfort and performance clipless is light years ahead (remember I hang out with you over at OldRoads so I don't automatically subscribe to new=better). The comfort part is obvious and if you want your clips/straps to be as secure as a decent clipless system you have to snug them up pretty good. As I'm sure you'll agree tight straps are not always easy to pull out of either. In fact it's quite a bit harder to get out of than a clipless system.

Clips/straps on a commuter make sense as you can ride with any shoe though Looks are large enough to ride in sneakers if you really want to.

The advice about unclipping early is very good advice.
