I ride in the city, and I don't ride fast at all, but it's much easier for me to get going at a green light faster than someone with clipless. They might go slightly faster, but it takes them longer to get going too, what with having to clip in and all.
Clipping back in is easy with a little practice. I find there's no time penalty there. And being clipped in makes quick acceleration easier, so there you go.
