[i]That's all well and good, but the Halo Array covers a much, much larger area than the Death Star. The results are what matter, not the numbers. The Death Star destroys a planet, but Halo wipes away all life larger than a millimeter within 25,000 light-years, triggering the activation all other Halos within its range. Furthermore, there have been exactly two Death Stars. The first one took twenty years to build, the second one took three years. Halos are built in a matter of a few months. It's pretty obvious which civilization has a better industry. [/i]
