Katanagatari - because it was just great. Character development, concepts, fighting scenes and plot - everything was well planned.

Bakuman - it is not finished yet but i can't find better series to take this spot. It has tension, love stories, comedy and serious stuff mixed together in great proportions and pacing.

Tegami Batchi REVERSE - setting is so unusual and fresh, soundtrack is just pure greatness and it is pretty solid series.
