Having ridden both, I recommend the Candy's. While both are perfectly fine, I found myself irked by the definite feel of loss of power transfer from a start. On the track I find this to be even more noticeable.

Also, depending on the stiffness of your shoe and your weight and riding style, mild hot spots may occur with the regular eggbeaters since they lack a platform. Around the city, I find that they'd be perfect but for anything over 50 miles, I'd want a more stable wider platform for the long haul.

Thus, the Candy SL's are my pedals of choice.

But I don't think you can go wrong with either.
