Both shows feature a intelligent story and take themselves seriously .Both are long and a bit slow paced epic sagas .Both have excellent character development and both touch the surface of many philosophical questions/ideas.
Fullmetal is a bit more relaxed and shounen-like but should you like the one you will most likely like the other one too .
