Greatest Total Drama Villian: Heather V.S. Alejandro

Who do you think is the greater villian. I think that Heather is a greater villian, as she is partially why Gwen and Trent broke up (she kissed Trent remember), and she's the ORIGINAL, and NO ONE can beat the original. What are your opinions, and who do you think is the better villian? And if you think Justin or Courtney is the worst villian than feel free to say so! So who do YOU think is the greatest Total Drama Villian?
