If there's one major aspect of Star Trek that's better than Star Wars, it's this:
In the ST EU, there's no major effort to make each and every storyline canon, there're no stupid retcons made to mesh incompatible stories/histories together, and there're no concentrated efforts to make each and every era outside of TNG and its spinoffs more like TNG and its spinoffs.
Compare that to the SW EU, where each and every story has to be canon, where every single incompatible story/history has to be retconned into fitting together, and every era outside of the PT has to be reconfigured to match the PT.
