It is built for the player with max Missile Specialization. I have not tried Reaper spam as an Aurora can do, but it is very good at Harpoon and MIRV spam. Gryphon is Starsector's D&D wizard who casts all spell slots in one fight - the five-minute adventuring day. The Gryphon is built to blow through its CR in one fight. If you do not want to do that, there are better and more efficient options such as Dominator.
The Aurora needs the ammo nanoforge special instead of its dubious high-energy focus. Most of its power comes from missiles, not the meager two blasters it has. Also, the Gryphon and Aurora appear very similar.
