Empire's SE definitely is the least vile of the three. I didn't mind seeing the wampa too much, except that the continuity between the original puppet and the guy in the suit isn't quite there. It makes me wonder exactly why they couldn't have done that in 1980. Could a wampa suit have been that hard/costly to produce? But, yes, not seeing it was pretty suspenseful, but it doesn't lose much by seeing him.
