Tony Baxter ranks up there as well. Joe Rhode is decent, but I do take issue with some of his latter design choices, such as making FOP where it doesn't have alternative options for those that are larger, wheelchair bound, etc. All of which could have been accommodated and kept the theming.
I can certainly say that the projects Tony Baxter has had creative involvement with have been the ones I’m most fond of, ‘especially’ the original Journey Into Imagination & Splash Mountain. So on that note, I’d probably choose him. ‘However’ there are many imagineers I love the works of, those including Joe Rodhe, Steve Kirk, Josh Shipley, and Ethan Reed. And of course, can’t forget folks like Marc & Alice Davis, Mary Blair, Rolly Crump, and Claude Coats. Many great talent.. just a shame the way upper management’s treated them all. Hence why most of them have left or have dropped to consultant roles now.
