Attack on Titan has a pretty similar art style and feel, minus of course the high technology FMA has by comparison. Code Geass is also great if you want a bit more futuristic take. Also has some of the best music in anime.
Silver Spoon is by the same author! It's a different genre for sure, but it has the same good writing and storytelling. In terms of genre another good one might be HunterXHunter?
