Akame Ga Kill - I am watching right now and I enjoy it so far
Tokyo Ghoul - I have watched both seasons and it is among my top 5 favorite anime
Sword Art Online - You have probably already given it a shot if you watch anime, some people like it, some people don't. I have enjoyed the entire series so far.
My list of anime that falls into what you are looking for is pretty limited because I mainly watch Romance/Slice of life anime with my girlfriend and have not seen very many entire seasons.
