Tiers were all over the place in Super. I remember seeing Chun, Bison, and Honda claim the #1 spot in several different tiers. Than Akuma, Fei, Cammy started making a lot of noise when people realized how good Cammy and Fei are and how good Akuma still is.
I remember when video of Mago's Fei started surfacing everybody was making comments about how they feel sorry for Mago for picking up such a weak character lol. Then you had characters like Abel and Rufus who were contenders and had ridiculously good 2nd Ultras. And Viper and Seth were actually around and very good. But but Krone, Latif, and Poongko hadn't yet became the contenders they would later become to better represent those two characters. If Super had more time it's hard to say who the top 5 would be today.
