Should've added a poll to this.
Anyway, I would personally have an aimbot that never fails - given that it's a 360 degree aimbot, and not a 180 one, though I can see who would want superbullets. It really depends on your actual accuracy, if you can shoot thru walls then you would probably need nametags/chams, but with an aimbot you would need no other hacks.
Final Answer : Aimbot.
