I would think that warp speed & hyperspace would be comparable, so an Interdictor cruiser should work on the ST ships. Both Uneverses had lasers so they are the same. phasers should be comparable to blasters with the blasters having a slight edge only because as a short blast rather than a steady beam, it would be a little harder to find the shooter in ground combat. Photon torpedoes & proton torpedoes should be about the same as well. The biggest difference I see in weaponry would be the ion cannon/disruptors. They would be comparable to todays 'dirty/clean' nuclear weapons. A 'dirty' nuke would be comparable to the disruptors because not only do they cause loss of life, they do considerable damage to property as well. 'Clean' nukes would be comparable to ion cannons because they concentrate on electrical disruption & wouldn't cause as much property damage. Both Universes had cloaking technology even though you didn't see it in the SW movies. Everyone I've seen in this thread seems to be concentrating on Q & his 'god like' powers. What about all the other 'god like creatures in the ST Universe? I don't remember all their proper names but there was that greek god, the Organians, Tremaine, those lava/rock creatures, the Metrons, et.. I think all the ST 'gods' would sit out on a battle like you describe because THEY would all be too busy fighting each other to be able to influnence the SW/ST battle.
