Right now I am torn between 2. I love FMA: Brotherhood but my friend recently got me to watch Durarara (sometimes called DRRR) and it has so many characters that are just amazing. I recommend both to anybody. FMA is action of course but Durarara is more of a drama if anything I guess.
I really can't tell, Another (anime) was really good, but right now I'm watching black butler and the first few episodes really surprised me. After that the excitement sort of died down for me a little. Deadman Wonderland was pretty amazing too to be honest. I purposefully excluded animes like one piece or naruto or fairy tail. They seem so big I wanted to give the others some recognition. I don't think sayonara zabuza sensi was really amazing, but the part with the chain of stalkers was hilarious.
