Of all of those, I've only been to 4 - Sci Fi, Boma, Crystal Palace and Whispering Canyon. I like all of them. We had a bad service experience at Boma the first time we went there (REALLY bad service), but we tried it again because the food was so good and got a wonderful server to go with the wonderful food the 2nd time. We weren't wild about the character interaction or the long buffet lines at Crystal Palace, but the food was very good. Sci Fi and Whispering Canyon are FUN. Nothing spectacular about the food (in fact, Sci Fi managed to ruin a turkey sandwich), but a good overall experience. Sci Fi is my kids' favorite restaurant at WDW after Trail's End (which may tell you something about their culinary tastes).
