Dude, Ken is lame. He's practically the same as Ryu without any of the plot relevance and he just became so typical to see used because he was incredibly easy to use! A boring second banana does not benefit from overexposure by bad players.
Dan's way more interesting and enjoyable. He's ballsy enough to be focused entirely on pointless taunting, he's almost always low tier so that choosing him and winning's generally bragging rights, he acts goofy, wears a bright pink gi... all around way more entertaining.
Even how he was made was great! SNK copied concepts of SF in their Art of Fighting series, so in concept art for SF, they made a random new character shown by Sagat beating the crap out of them. Said character's got the head of one protagonist of AoF and the body of the other one, and somehow from this art he becomes a full fledged character. And then he even steals the moves from the AoF guys.
