Honestly, since directly after the dubstep craze era, there has been suuuuuuch good music, because I feel like that's when electronics became much more mainstream for ALL musicians to play with. Prior and during that time, I think a lot of electronic music was about experimenting with sounds. But during that era I think was when everyday musicians got comfortable with the soundscapes, and started incorporating all their other music knowledge and to make more varied, complex, and interesting stuff.
The problem is just finding the good music, since it can be so quick for anyone to produce and distribute it. There's just way too much.
