Well I'm a Star Trek fan, mostly just for The Next Generation, so I guess I'd have to pick them. Some people found it duller than other series, but I really LIKED the way they tried to find solutions for very difficult problems, and all the different aliens that showed up. But it really came into it's own in the third season, wit one major storyline that dragged from the end of season 3 to the start of season four (known to many a Trekkie as 'the long summer'.) Also, Data was cool.
On the other hand... lightsabres are EXTREMELY tempting and props to Lucas for making Star Wars the epitome of the A Hero With a Thousand Faces storytelling theory IN SPACE.
There are actually conventions now for both groups of fans together which is nice
