Tough to say. I think Ezio beats Altair for the reason that there were 300 years for the Assassin fighting techniques to advance. Ezio has a wickedly leathal finesse and grace that Altair just cannot match. Between Edward and Altair, I’m going with Edward in this one as well, but mainly because Edward is a natural fighter who could kill an Assassin without training and by the time of Black Flag, Assassin combat techniques have endured and advanced in the +500 year gap between AC and AC4. Between Ezio and Edward is a tough choice. Again, Ezio has finesse, but Edward has natural abilities that only get better when he is trained. I think what will decide it here is brains. Ezio came from an Italian Renaissance middle class banking family. He was raised in an environment that valued education, study, the arts, and the like. Being well educated will help him come up with more unique solutions to challenging obstacles. Edward was a poor Welshman sailor and most likely uneducated. He knew how to fight and sail, that is it. There were several times when Edward was outwitted by his opponents which usually resulted in devastating consequences. I love Edward, but I am going to have to give this to Ezio, for his ability to plan and adapt to new obstacles. Winner: Ezio Auditore.
