In any case, Steins; Gate is on the top spot. Then, in random order: Death Note, Psycho-Pass, Bakemonogatari, Nana, AnoHana, Code Geass and more...
For me, short animes are basically less than 50 episodes. By such, I won't consider FMA. Especially, because if I did consider <100 episodes, my list will get never-ending.
