I enjoyed Darker Than Black as well. The show was really good at integrating various anime tropes believably into its own universe. Yoko Kanno did the music so that tends to make shows even better.
Among my top favorite anime: DBZ, AnoHana, Robotic;Notes, Usagi Drop, SAO and FMA:B If we include movies, Whisper of the Heart, Wolf Children, and My Neighbor Totoro is added to the list.
Edit: I wrote a review getting excited to talk about Death Parade.http://www.maiotaku.com/mytopics/24222
