The Good: Crank Bros. always stand behind their product and have always had excellent service.
The Bad: Thick, overpriced, grip is lacking, gimmicky plates, and weight.
5.10's can make a crappy pedal better but the question is should they? No, just buy a lower profile pedal with better grip from the get go. They could lose a bit of weight if they didn't stick to their guns about the gimmicky plates.
I have run Deity, Atomlab, DMR, Kona, Shimano, VP, Spank, Eastern, Odsy, Truvativ, and more. I would run anything else before these.
