My daughter who was 4 when we last went to both parks much perferred MIB to Buzz even though she likes Buzz. The movement of the ride was alot more fun for her. Disney could have made Buzz from scratch by tearing down the building and starting new but did it on the cheap by using same type of ride mechanism. When ive been to both parks MIB was alot busier but with FOTL it was great to ride it numerous times to try to best your score. I guess everybody will have their own perferences but i see Universal as trying to create new experinces while disney is satisfied with getting by. As a example TDS gets a pooh ride that is new while we get a pooh ride thats runs on the same track with cutouts and a bigger store.
