Attack on Titan, Full Metal Alchemist and Sword Art Online was good until halfway through the first season. I like story and good plots, and those are the best I've seen so far. I just started Death note through, and it really looks good.
Shiki or FMAB or Another, Another probably has the weakest plot but I find it entertaining. Shiki is really good just for a psychological pull and gave me a lot to think about... I also love vampires that are actually vampires. FMAB because it was so good at the end, I loved the last half of the series the most.
When it comes to Comedy, The Devil is a Part-timer takes first place. Then there's Psycho-Pass for Psychological animes. THERE'S JUST TOO MANY GOOD ANIMES! Fullmetal Alchemist: Brotherhood is an all-time favorite, though.
