I like both. It really depends on what kind of atmosphere you're looking for, and what type of food you're looking for.
Rose and Crown is more relaxed (and loud), and Chefs de France a bit more "formal" (at least for EPCOT). Check out the menus to see what you'd prefer for food... I think the quality is good in both restaurants. One thing I do like about Chefs de France is that they bring Remy out to interact with the diners. Pretty cool, and pretty fun. I think they're still doing this anyway.
