My vote remains with Jaime Lannister, I maintain that he outskill Leonidas:
- Prime Jaime is better than Bronn, Black Lorren and Garlan Tyrell in skill, swordsmen who can hold their own against three or four men simultaneously (and not one by one)
- Should be better than Rogar Baratheon in skill, who is so skilled that despite his exhaustion, weakness and illness he can easily outskill and kill with his double-bladed ax a man armed with spear and shield and in good shape.
- Should be comparable to Barristan Selmy in skill (superior, equal or inferior, we don't really know, but in any case they should have a very close level), who is 61/62 years old easily killed and outskilled with a wooden staff a dangerous killer taller, younger and heavier than him and who was armed with a sword
- Should be superior in skill to the wife of Alaric Stark who, at just 12 years old, attacked a pack of wolves and killed two.
- Should be superior to Steffon Fossoway in skill, who, according to Duncan the Tall (Dunk and Egg stories's protagonist), can find a man's weakness with just a glance
- Should be superior to his uncle Tygett Lannister, who killed four men including a knight, in several battles when he was ten years old, and Josmyn Peckledon, who had killed two knights, wounded a third, and captured two more when he was only fourteen years old during the battle of the Blackwater
- And he should be superior to his ancestor, Tybolt Lannister, who can defeat a knight armed with a shield and a sword, with just a shield
