I think the conclusion the the hopping rabbit AA in WDW helps give an edge to thier ride is stupid.
If you ever get the chance to ride the SM in the MK take a close look at it. The support structure sticks out ruining the show. I know WDI was quite proud of this AA, but I find it to be one of the worse executed designs they've done.
Still though, outside of how it fits in each park, looking at the ride alone on its merrits, I like the MK version better.
