Okay, first of all, Descendants of Darkness wins for funny world-building details. Death gods want to go to earth to eat dessert, use credit cards, and flirt with girls (in addition to doing their job of sorting out souls or something). This anime also covers a ton of psychological ground, dealing with death, rape, suicide, murder, illegal organ transplants, homosexuality in both a bad and a good way, and trying to move on after extreme trauma.
My favorite character is Kurosaki, who has to decide whether to make his afterlife about revenge or about friendship, and his journey is very convincing, though the protagonist Tsuzuki also interested me.
However, while it was definitely enjoyable, I can't say this one was one of my favorites because I wasn't a huge fan of the art and there were way too many unexplained instances. It was also very stereotypical in its dealings with gender, which always irritates me.
