I don´t want to remind you, which of these 2 players still used his former main character in AE and which one picked a top tier for AE.
And concerning counter picking, if you are in a tournament with a nice prize money and you are now in the finals. Let´s say, you would main Bison and your opponent is a Guile player, would you still use Bison, despite the fact, it is a 8-2 matchup for Guile?
Your character choices have to be done in a way, where all matchups can be covered with nearly no bad matchups. If you think that your main doesn´t do well against character Y, then pick someone else for this matchup, who does better.
About Filipino Chump, if you are maining a char, who doesn´t work well with the metagame of SF4 and has also a lot of bad matchups(Abel, Hakan, Makoto, Yun, etc), then he will have a hard time, but in the end, the player is himself responsible for his defeat. Never blame the matchup difficulty. Another thing is, FChamp deserved it.

This is something, some people can´t admit and Fchamp is one of them and also one of hardest thing in the FGC, according to Daigo.
