Camp Chef Gridiron vs Weber Slate: twice the price = twice as good?

I'm in the market for a griddle, and fell in love with the Weber Slate. But then I saw the Camp Chef, which is about half the price of the 36" Slate. I know the Weber is good, but is it twice as good since it's twice the price? I only want to buy once and cry once, but double the money is giving me pause with the Slate.
