I would be the Ragnorok. COME ON- a ship THAT advanced would have an artificial intelligence/guidance/superweapons command center. And I could kick ass and punch my way through otherwise impenetrable armored, force-field shielded monoliths. Who doesn't wanna do that?
And considering you have NO IDEA where the security cameras in that thing are.... plus, being a super-cool machine, literally unique in the universe, and you KNOW all the best upgrades will be mine first

And an appearantly infinite power supply... yeah, that'd rock.
