To compare the platform side of my Shimano 324's to Crank Bros 5050's, the bigger wider (102mm x 96mm) Crank Bros wins by a mile. That being said, shoe choice is a HUGE factor. I can ride either set in Keen commuter shoes (very stiff midsole) no problem at all. If I wear Walmart sneakers the 324's are uncomfortable after a couple hours. My next set of platform pedals will be the VeloOrange Grand Cru Sabot (100mm x 100mm) both for looks and the little bit extra real estate. Crank Bros model Stamp Large is 111mm x 114mm and is one of the largest I've found, but it has a very large cutout profile and I think we are back to sole stiffness playing a big factor with those despite its size. Comparing the 5050 to the Stamp its clear that overall size and total surface area are two different things.
