It really is a matter of taste. I had to force myself to watch a full season of Sword Art Online. It has it's sweet romantic moments. But to me, it is a wish-fulfilling feel-good kind of family-friendly story. It's easy-to-watch cutesy fare like K-On.
For a similar fantasy/game romance sim setting, Re: Zero Kara Hajimeru Isekai Seikatsu has been keeping my attention this season. It may be rehashing the idea of a "save point," or "do-over" a la Ground Hog Day/All You Need is Kill (The Edge of Tomorrow)/Boku Ga Inai Machi (The town where I am not there/Erased). Yet there is good mystery and problem solving element that keeps me engaged.
I like Attack on Titan; the anime far surpasses the manga in art quality, but I don't like the way it diverges from the actual plot towards the end of the season (Claymore and Gantz had a similar issue). I don't know if I would call it overhyped, and I wouldn't say it's the best thing ever. But entertains me in the sense of the the scale of imagination. There is a deeper mystery of why do titans exist to begin with, where do they come from, and why doesn't anybody (except the shadow governor/ruler) know the real history of how things came to be in Attack on Titans world.
Berserk is one of my all time favorites by far. I'm looking forward to the reboot, where it picks up where both the 3 movies and the old TV series left off. But Berserk, like Hunter X Hunter, One Piece, and Hajime no Ippo, is falling into that category of manga where you wonder if the artist is going to die before he ever gets to finish the story.
