Hard to beat because they break and you can't ride your bike.
Egg beaters are nice for the availability of all parts used in every pedal. You'll need that when they wear out and break all the time.
Okay, all bashing aside:
Crank brother's pedals leave exposed parts dangling down below. If you live in a rocky environment, or pedal strike often, this can be problematic. The tops of the springs are where your pedal is supported. This means that the "platform" under your shoe is quite small. This can cause wear to the bottom of your shoe as well, eventually causing play to develop. Crank bros has "fixed" this problem by selling you a special plate you place between the cleat and shoe.
Shimano pedals support the shoe through the cleat, or the body of the pedal. Depending on the model of the pedal, the exact shoe you're using and how it interfaces. Not only does this eliminate or reduce shoe wear, it can improve the feel under your foot. Super stiff carbon shoes can't tell the difference, but softer shoes can.
Also the bearings in crank bros pedals are ****, shimanos are better. The best ever? Meh, not as good as Time in my opinion, but the complete package of spd is pretty nice.
And for those who buy crank bros for weight savings are just ****ing losers.
