I have to admit, it's been a while since I spent some time with Dubstep, but from back then I can confirm what Tai said in the comic. I prefer UK Dubstep over the typical US Dubstep.
Great artists I remember are Bar9, Mt.Eden, Nero, Flux Pavillion and such.
UKF Dubstep on Youtube is a great way of looking into UK Dubstep.
