1. There's only one fully operational Death Star. 2. Star Trek ships are more numerable and generally mount more weapons than equivalent Star Wars ships and are much more agile than Star Destroyers. 3. The innumerable amount of Borg drones could adapt faster to Imperial or Rebel technology. One, maybe, two Death Star strikes before it becomes useless. 4. Starfleet can train troops faster and more effectively with the holodecks. 5. One letter: 'Q' [2]. 7. You never see Janeway in a tacky metal bikini... (thankfully!) 8. The UFP has better methods of interogation: holodecks.
