The belt is a little lighter than a chain, but the pulleys are a lot heavier than sprockets. Also, in my experience, belts break more easily than a chain when they are stressed or damaged by something like a rock getting in the pulley. And they don't handle any misalignment very well either.
They are quiet though.
