There is as much variety in dubstep as there is in techno.
Like any genre if you only see the surface you see the shit cos it floats.
People who don`t know techno might assume it`s all shite like pedro delgardo and such because it is commercial and more present.

Dubstep covers all sorts of sub styles so you just have to investigate.

the list can go on, there is so much variety and good stuff.
