Character Set-up [DNP]

Who should I stay with? Megatronus, a noble ex-teacher who fights for an all autonomous Cybertron, joined by his loyal crew, or the merciless Optimus Prime, a tyrant among tyrants with his band of misfits & murderers whose aim is to pillage & plunder their home for everything it has? I am in no position for this line of thought as the two stand before me.
