For me,Tezuka Kunimitsu.Even though Tezuka lost to Sanada doesn't mean that Sanada is better than Tezuka!Coz many people thinks that the victor will always be better.But for me,that's not how it works.Its how you played and the condition of the players.See,if Tezuka does not have any injury before,Tezuka Phantom will not cause that pain.Yes,of course it will hurt but not that hard because Tezuka Phantom re-injured Tezuka's arm.And because of this,he couldn't use the Zero Shiki Serve during the game!Its just like his fight with Atobe,his injury is the cause of his lost.And I think with his injury completely gone,I think he can even beat Yukimura.
