Is the assumption that you can pick who you are in that universe too? B/c as an average joe star wars would suck, especially if the Empire comes knocking at your door or you're a vapor farmer. Even life on Coruscant (as centre of the SW galaxy, like Earth would be to ST) is filled with ghetto areas. Same goes for the comic book universes. Unless you're also superpowered, chances are your life expectancy is 30 tops...every week someone's tearing shit up on your block or rewriting the history of the universe. The life of the average citizen in the Federation seems more agreeable, there's no more hunger, need/want for possessions (according to Picard in some episode)...and they have the holograms do the shit jobs.

If you're the same person but transported to another universe, I'd pick Futurama. Or Fifth Element...flying cars, shapeshifting aliens, half naked Milla Jovovich and I can still get some McDs or flyby chinese food while some freaky blue skinned bitch sings a operatic trance mashup ...sign me up!
