Avatarr. I enjoy Psychopath in game, and Avatarr annoys me, but the bottom line if you had to actually fly with him, Psychopath can't be trusted, while Avatarr probably would have your back. Also, Psychopath would probably just laugh at you and tell you you're pathetic if you asked him for help and laugh as you got blown to space dust, unless he actually needed you to live, he wouldn't care about whether you live or die one iota, and might even enjoy putting a missile up your tailpipe for ****s and giggles if he was in the mood.
Psychopath would love to watch the whole universe burn.
