I ride Look (delta) pedals. I prefer them to spuds because they feel more solid, more connected to the pedal, and with stiff soles the greater power transfer is noticeable...
BUT
...I ride on quiet roads, no traffic lights. I go out, do my ride and come home. I very very rarely unclip, sometimes at junctions or when I stop for a pee. When I go out with the club each month for our restaurant ride, Look cleats are a pain. I actually take a pair of judo type slippers to put o,n whilst in the restaurant (much to the amusement of my clubmates!)
IF I were making the decision again, I'd probably opt for spuds. WAY more convenient off the bike and, for my purposes, negligible difference on it.
