I use Crank Bros 'candy' pedals on all my commuter bikes now, even the winter bike. I have lots of stops, too, but I usually don't need to unclip as long as I can balance/roll slowly for a couple seconds. However, it's really easy to get in/out of the pedals. You'll get more and more confidence with practice. I only unclip now if I know I'm going to be stopped for more than about 5 seconds, but I used to unclip well before rolling up to an intersection.

What sold me on the clipless? After using them on one bike, I found I kept sliding my feet right off platform pedals as I pushed and pulled through the top and bottom of the pedal stroke. I don't like the idea of having my feet come off the pedals and potentially going into the spokes. Also, the extra speed I get from using clipless means I can almost keep up with the speed of traffic on much of my route, so it cuts way down on the number of interactions I have with cars, and our relative speeds are very similar, meaning that motorists have lots of time to notice me, and aren't so aggravated about immediately trying to overtake me. That's a really nice safety feature in my mind. The Candy's also have enough of a platform that you don't really need to put on your bike shoes if you're just taking a quick trip somewhere.
