I like Black Butler più I think, but Death Note is really awesome too. I've never seen the other two, so I can't really judge. And the picture is really awesome.
definitely code geass. c.c, kallen, anya and shirley and lelouch rock! the rest of the cast are okay i guess XD. lol the only picture i can find with the five of them in it.
My preferito is Black Butler - Il maggiordomo diabolico (Black Butler)!! But I really like Death Note and I've been told that Code Geass is really good.
Out of the three,my preferito would have to be Code Geass. Though I don't care much for the secondo season R2, the series was quite interesting and unique. It makes it to number five on my preferito Anime lista and two of the characters (one male, the other female) both make it onto my preferito Anime male and female list.
I also like Black Butler - Il maggiordomo diabolico (Black Butler), although I prefer the manga. The Anime adaptation was quite fun to watch except for the secondo season (Kuroshitsuji 2 o Black Butler 2) ending. One of the worst ways to end a series in my opinion. But overall, I enjoyed Kuroshitsuji. It makes it to number sex on my preferito Anime list.
I have not seen Soul Hunter though I plan to watch it in the future. ^^
