When people list their favorite Screamo/ bands, why are Dillinger Escape Plan and Sikth not mentioned?

I don't listen to much Screamo/ whatever you want to call it, I'm more into metal anyway, but I do like Dillinger Escape Plan and Sikth, however they almost never get mentioned in these "who's your favorite screamo/" type lists, am I missing something here? Are DEP and Sikth not far superior to most screamo & bands that teenagers are into?
