Who was the better leader, Visser One or Visser Three?
I am with Visser One through and through. Having a human controller, he has an advantage on knowing how to deal with humans. Visser Three's lack of empathy combined with his extra large ego doomed it to his failure. His first appearance, the one when he killed Elfangor, could've been prevented if only he acted with his reason. Morphing a large alien being near a mall is dangerous, but he did it anyway. Near the end of the series, as he increased the production of Controllers by force, he also produced more enemies due , leading to his fall.
