Pedals are really user specific and there is a big difference even within Speedplay models. My feet are not symmetric in the way that they rest on the pedal. I need the right to allow a lot more heel-in/toe-out than the left. I use frogs on my commuter and offroad bikes. The large amount of float works well and I like the low stack height and two sidedness for instant clip in at stoplights. I use zeros on a purpose built road bike and love being able to set in and out float differently for each pedal...gives me really good control on rough roads or frantic twisties. If my legs and feet were more symmetric, this would not be so important to me. Lots of good pedals out there...I can't say Speedplay is better or worse for you but they sure are for me.
