I use both Candies and Eggbeaters. You will not notice the platform when clipping in as it rotates out of the way. I agree with Kiwi that the platform gives better stability when not clipped in.
The only disadvantage I've found to Candies is that the platform compresses snow into ice on the bottom of your foot. Mud shedding is the excellent for both pedals, but snow tends to compact so I'll switch to Eggbeaters if I think I'll have some snow banks to navigate. This probably isn't helpful as it sounds like you're using these with a road bike but just sharing . . . .
