Para no hablar con opiniones que al final son subjetivas pongo mejor números:
Star Wars: Acclamator troop transport
Light guns: 300 million GW (6 megatons per shot, 24 guns, assume 1 shot every 2 seconds for time-averaged power output rather than peak output)
Heavy guns: 2.4 million megatons (200 gigatons per shot from each turret, 12 turrets)
Sublight acceleration: 3500G
Operational range: 250,000 light-years (before refueling)
Shield heat dissipation: 70 trillion GW peak
Reactor power: 200 trillion GW max
Max hyperspace speed: not stated (however, the ability to travel "halfway across the galaxy" in a matter of hours as demonstrated in ANH, TPM, and AOTC requires speeds in the range of 10 million to 100 million times c).
Star Trek: Enterprise-D
Main phasers: 3.6 GW (5.1 MW per emitter, 200 emitters in the main phaser array, 2 full-sized saucer arrays and 3 smaller roughly half-size arrays on the stardrive section). Note that phasers appear to have a chain-reaction effect so their raw power output may be deceptively low.
Photon torpedoes: 64 megatons max theoretical (based on 1.5 kg antimatter payload)
Sublight acceleration: 1000G (design goal, p.75)
Operational range: 2750 light-years (7 years at warp 6 before refueling)
Shield heat dissipation: 3311 GW peak (473 GW per generator x 7 generators)
Reactor power: ~4 billion GW at max warp 9.6 (scaled from the warp power chart on p.55 which uses units of joules for power; we assume this is a simple mistake). From the chart, their fuel supply for 7 years of warp 6 cruising would be roughly 2E23 J (enough to run an Acclamator's reactor at full power for just 1 second).
Max warp speed: ~2000c (warp 9.6), sustainable 12 hours for a single sprint of roughly 3 light-years. This appears to have increased to roughly 3000c for newer ships such as the Intrepid-class.
