Now that all of the series' I was following this season have ended, I think I can rather confidently say that School-Live! and Himouto! Umaru-chan are my joint shows of the season. Both are on complete opposite sides of the emotional spectrum, but both did what they did excellently. I've actually always found zombies and "zombie apocalypse" stories to be incredibly boring, but School-Live! managed to present them and mesh genres in a way that really worked.
For reference, the shows I watched this season were: Charlotte, Durarara! X2 Chapter 2, Food Wars, Gatchaman Crowds insight, Himouto! Umaru-chan, Monster Musume), School-Live! and Symphogear GX. I am currently two-thirds of the way through Shimoneta, but won't be able to finish that one until I get my laptop back from repairs. If I had to rank them, it would be something like:
1: Himouto-Umaru-chan!
1: School-Live!
3: Monster Musume: Everyday Life With Monster Girls
4: Food Wars
5: Durarara!! X2 Chapter 2
6: Gatchaman Crowds insight
7: Symphogear GX
8: Charlotte
Charlotte would have probably made it to 5th place if not for the time-leap stuff and where the series went after that. Conversely, Gatchaman Crowds insight would have likely been right at the bottom if not for its last few episodes. Also, while I did enjoy Durarara!! X2 Chapter 2, I don't think it really held its own as its own thing; it felt more like a bridge between the first and third cours.
That ranking isn't to say that any of the series' were bad - even though I've complained about Symphogear GX in other threads, I still enjoyed it. Well, Charlotte's last leg was pretty bad, but that's about it.
