That is the other reason I don't care for Tier list cause everyone has their own criteria for the best.

I'm certain Tidus and Kuja are really easy to use and spam but I'm more interested in playing as characters like Cecil and Garland who seem more challenging to play correctly. Sephiroth and Kefka have some obvious flaws if you watch some gameplay videos but at the same time, a capable player can learn how to turn it into a strength.
