I suggest going onto Mixcloud and listening to a bunch of mixes with the Drumstep hashtag to check out for yourself, genres are really hard to describe in words - and are imo going to become meaningless in the next few decades.
That being said, it's honestly better thought of as drum and bass in halftime than dubstep at drum and bass tempo, because it came out of the DNB scene, not out of Dubstep. Beyond that, the people who spin the songs are gonna have the most options - find tracks stand out, go buy them, and deconstruct them!
