What anime should I watch now?

I have seen Fairy Tail, Ao No Exorcist, Shugo Chara, D. N. Angel, Kuroshitsuji, Kaichou Wa Maid Sama, D. Gray Man, Black Cat, Ruroni Kenshin, Black Lagoon, Angel Beats, Detective Conan, Air Gear, Naruto, Naruto Shippuden, Fullmetal Alchemist, Fullmetal Alchemist:Brotherhood, and lots more. I have trouble trying to find the anime I want to watch so I decided to use this to find out what I should watch. I would like one close to Ao no Exorcist or D. Gray Man.
