Kei Takishima VS Takumi Usui

I've noticed that the manga,and anime have two very powerful men in history. But I like to ask you this. For those who don't know Kei Takishima, he happened to be the best student of being number one student in his entire school of Hakusenkan. Kei came from S.A: Special A. For those who don't know Takumi Usui, he's happened to be the most popular boy in Seika High. Kei and Usui got a lot in common. They both scores excellent grades,and beyond that,excel at sports,successful cooks,both very strong,almost at everything,and they both have feelings of an extraordinary women in the form of Hikari Hanazono and Misaki Ayuzawa respectively. In the game of Yugioh, if Kei and Usui were to be matched up in a Duel Monsters Tournament, which one of these guys do you think will win the duel?
