Familiarity: I've put it through the wringer
They're really easy to clip in and out of. I'm a first time clip-in user, and it was really easy to get used to them. Additionally, the pedals are big enough to use with normal shoes if you're casually riding your bike to a friend's house and don't want to wear clip-in shoes.
