I've missed Fantasmic more than I've seen it. :-\ That isn't to say I dislike the show though... For some reason we always seem out of it by the time night rolls around at MGM.
SpectraMagic I enjoy because it reminds me of the old MSEP but is more sophisticated IMHO.

Also of the "smaller" shows, the show at the Biergarten (at least twice a trip) and the British Invasion (there are times when I've spent a good chunk of a day at the London Pavillion).
