I'm loving "Yahari Ore no Seishun Love Comedy wa Machigatteiru", it is the kind of series that hits close to home. Plus I love Hachiman's character a lot. Enough for him to be my favorite male MC this season.
Also liking Plastic Memories (One of the writers was part of Steins;Gate btw) and Unlimited Budget Works, though I am going to let this one finish first.
As much as I like Fate and Dungeon, they can't beat the sheer ridiculousness of Food Wars. I can't say anything about Gintama yet, I'm still watching all of the old episodes, and I haven't even started Yuki-chan yet. (Yes, yes, I'm a heretic and blasphemer, I know)
I really am enjoying DanMachi, but Hibike! Euphonium takes the top spot for me. Not only is KyoAni's art and animation as beautiful as ever, but it's got a solid story so far, and the nostalgia from my own high school symphonic winds days is strong.
