By some weird setup I have four sets of Crank Brothers pedals on two bikes.
Egg Beaters- Not able to ride without being clipped in.
Smarty - Pretty small platform and not a good pedal to ride no clipped in. I imagine the Candy's are similar
Enduro - My favorite all-around. Ok to ride without clips, though I it depends on your shoes and the distance.
Mallet- Though they may look stupid on my Cyclocross bike they are my favorites. Big platforms works decently without being clipped in and when clipped in they have a big strong platform which is nice to just cruise on.
