I still don't know what the hell dubstep is.
If you're totally foreign to what dubstep is then it's a music genre that started in Britain, the name dubstep has roots in dub, and 2 step. The 2 step drum pattern is what characterized dubstep and it usually featured basslines, or sometimes wobbles. The genre later morphed into different genres like brostep, complextro, drumstep, etc all taking influence from dubstep. The newer dubstep features (to me relies on) heavy bass that usually oscillates which creates a "wobble" effect. You can easily find a dubstep remix of all your favorite songs. Older dubstep was much more chill and has a more "reggae" like feel. Older dubstep was what you'd sit in your room and relax to, newer dubstep is the stuff they play at raves for kids all drugged on on MDMA, weed, shrooms, or whatever they can huff.
If you want to find dirty dubstep just look up Skrillex, borgore, datsik, or bassnectar. If you want some older more chill dubstep check out Burial, Joker, Zomby, Skream, or Benga. If you want to hear some artists that started in dubstep but later branched out then look up Darkstar, or James Blake.
My point by bringing up dubstep was that media evolves and it is hard to really compare the different "eras" because of their unique qualities and the audiences they cater to. You can love both you just need to check your pretentious (daedric) prince at the door.
