The newer Eggbeaters are nice and less problem-prone, but I ditched my old pair anyway, in favor of ATACs on the MTB and Aliums on the commuter.

I find the Crank Bros. designs are a bit inferior, at least in the long term. Somebody mentioned the bearing/bushing stickies (which ATACs have too, though, since they're mud pedals,) but either which, most two-sided pedals have two engagement springs, often four, while the four-sided Crank Bros. only have one. Which is sort of OK, but after a while, the two contact points wear down the tines, and the pedal gets all unspringy-like. Which is also sort of OK, if you don't mind rebuilding the pedals every year.

And using Eggbeaters offroad, they tend to unclip if you smack them on a rock or log, just by nature of their design.
