You're kidding, right?
I think the Egg is a good cooker, but I don't have any personal experience.
However, it is heaver than heck, difficult to move around unless you get one of those dollys (and then you have to be concerned about any steps you might have to negotiate).
It's expensive as heck.
And nothing cooks any better than the WSM regardless of price.
Now over on the BGE forum, they might tell you different.
(oh yeah, and they break! and there's that thing about flashback if you open the lid too quickly...)
Maybe I'm just biased...
