If both were the same price you would have to go Bichmann. I like the idea of the ease of cleaning since you are not dealing with the lip at the top like a keggle, and I never can get all of the grain out of the crevice between the keg side and domed top.
However, I could not justify spending the money, personally. I have a kid that will want to see Mickey in a few years, go to college, get married... you get the point.
