Like a lot of people are saying, a lot has to do with what characters you use and personal play-styles. Some people will just do better against some than others (like boxing, it’s all about styles). This will be reflected in their lists, since personal experience is really all anyone has to go one.
For example, most people consider MrJangara easily the best Cammy, but whenever I played him I beat him rather easily and wasn’t impressed (of course I do use Honda). Irvine Devereaux’s Cammy was much more impressive to me and much tougher to beat. So, for me, I’d place Irvine over Jangara, even though Jangara may be better in all his other match-ups.
Also, this idea would have been even better before SF4 stole a lot of our players, LOL. KJ out da 17th and Calipower, for examples, pretty much just play SF4 online now.
