Ugh it's so hard to choose. At the moment I like "Akatsuki no Yona" because I'm in a shoujo (young female targeted) mood. Feeling very romantic and lovey. Haha. Normally I'm into much more mature anime like Ergo Proxy, Claymore, Psycho-Pass, Fate Zero, Samurai Champloo, Attack on Titan, etc. I would definitely recommend Attack on Titan. It's very popular right now, has great character development, plot, enemy, etc. I would watch it again.
