They are all fun, but Stern Star Wars will keep you busiest the longest. If money is no option a pro or premium comic book art is the way to go. If you have the abilility to check them out after the end of the world, I would recommend playing both a pro and a premium if you can find them localish on pinside maps. The premium has the cool hyperloop, but the pro deathstar shot is substantially easier. I will also say that if you have kids 12 or under, absolutely go with the Stern Star Wars for the video clips. My young un's used to like to be the designated "button pusher" and tag team the game. The Stern game is great from a variety point of view as there are so many different ways to play it. If you don't like the combo multiplier gimick, just move it over to the death star and leave it there. Also, from a furniture point of view, think about where you will place this. The Data East in particular isn't a looker, but depending on the them you are into you may have a case for any of the machines.
Finally, think about what you want. One of my favorite all time games was the Data East Jurassic Park. It's ugly, it's clunky, but I just had alot of fun playing it. I have a Stern JP Pro now. It's fun too and much deeper, but fun in a different way. There is no real wrong answer and your mileage will vary, so get what you want!
