Akashi and Murasakibara play two entirely different positions. It can't be said who is the better basketball player.
I disagree with the statement above. Akashi is clearly the superior one because during the flashback, Akashi and Murasakibara had a 1 on 1. Akashi won and unlocked his "Emperor Eye" ability.
I read the question "How did Akashi get a yellow eye" and I have to say that Akashi snapped and then he unlocked his Emperor Eye. That being said Murisakibara was better than Akashi before he unlocked the Emperor Eye.
