Well, in all fairness, Link and Ganondorf rivalry extends through tons of games, compared to Cloud vs Sephiroth.
I love the Zelda franchise and FFVII is also one of my favorite games, but when comparing rivalries, it's even easier to see Link winning this one than he would normally in the character battle.
Despite the contests usually ending with Link winning they are still more enjoyable than a normal poll of the day, and it's fun to try to win some prizes.
