The main question is will you ever be walking in these shoes? If you are going to be using these pedals for getting out of your car, riding, then getting back in your car or for stepping out your door, riding, stepping back in your door the best option will be either Look or SPD-SLs. They provide more comfort, better power transfer, and more riding durability. But they are totally unwalkable. So if you are going to use them for commuting, or even just to stop off in a coffee shop the SPDs would be the better choice.
