>>11876202Blue was the best serious Champion. Iris was the best unconventional Champion. Their music reflects their personalities. Blue wanted to beat you no matter what. Iris just wanted a fun battle. They aren't things you should really compare to one another since they were designed to be conceptually different, although people are going to pick their favorites regardless.
Meanwhile my personal opinion is that, while I love Iris, I prefer having a serious Champion so Blue is the one I prefer even though I accept Iris for who she was.
