I dunno, in some cases you can really pack a LOT more into a ship, at significantly lower cost, using a lesser warp engine. Like 25%-50% more guns AND the ship costs maybe 15%-25% less, if you are willing to drop from say warp 6 to warp 3. A lot of the good specials and the regular/heavy beam weapon variants have hefty power requirements. Fusion beams are pretty bad in this regard.
If you zip around the AI and cleverly mass your swarm at just the right times, fast ships are great, you can really run circles around slow AI fleets. But I've had good success with cost-efficient juggernaut fleets too, you can get a lot of value for your dollar.
