From what I've gathered here and elsewhere, there's not going to be all that much difference in the food. They both end up changing menus so which one had more variety and flair the one time may not be the next time. Both have their good nights, and both have their bad nights, more good than bad. Both ran exactly 80% thumbs up, 20% thumbs down in the guide I bought. Both have a pretty loyal following when all is said and done.
I think when all is said and done, your decision really comes down to
Which of these do you want?
Mickey, Chip N Dale, Goofy, and Sometimes Minnie and Donald in the contemporary concourse with true soaring ceiling with a view of the monorail
Or
Pooh, tigger, Eeyore, and sometimes piglet in the conservatory with a beautiful garden in the middle of it
Or was it colonel mustard with the rope in the parlor. hmmm.
