I like the flip pedals because I can clip out if traffic is heavier, or if I'm on a family outing with kids. Right now I'm usually pulling a trailer, so I use the pedal side until we get to the trail then clip in once we don't have to worry about cars for a while.
the downside to combo pedals is that they have a tendency to rotate with the clip on the underside, which, if you want to clip in, is not a good thing.
