i think techhouse sounds pretty neat sometimes too, a bit unique for its genre.
trance is like...on a whole different level nowadays, although the trance fad (vocal trance in particular jesus) died off in favor of electro/prog house.
dubstep influenced electro-house (like really, imagine the typical cookie-cutter skrillex song but on every other electro-house tune) is the new thing though. they go as far as to even have a dubstep "breakdown" 2/3's of the way through the song.
