It's a very hard decision. Star Wars has the epic space battles, the epic stories, the epic video games, the epic comic books, and the epic Force; but on the other hand Star Trek has the epic Shatner, the epic intelligence, the epic movies, the epic TV shows, the epic comic books, etc.
Star Wars is more-so special effects driven, where Star Trek is more story driven, and I prefer story driven to who has the best special effects. My vote goes to Star Trek.
Kind of... but at the same time Star Wars has a lot more symbolism in it. It seems it has a lot more thought put into it than Star Trek.
Not to mention Natalie Portman is in it and OMG, I would sell my soul just to be in her presence.
