I said "this season" I LOVED Houseki no Kuni as I've been following the manga since chapter 1! However, it's last season's... Only good thing that's ongoing is Mahoutsukai No Yome which is still last season's...
Why? I can just give you the entire list of anime you should watch from last year, as his roundup left out some pretty good ones! Last year was great, but so many anime went under the radar, I can list them here for you if interested!
In random order including both famous and lesser known ones: Blend S, Boku no Hero Academia S2, Busou Shoujo Machiavellianism, Houseki no Kuni, Imouto Sae Ireba Ii. (hilarious but can get surprisingly serious at times), Juuni Taisen, Kenka Banchou Otome - Girl Beats Boys, Kobayashi-San Chi No Maid Dragon, Kono Subarashii Sekai ni Shukufuku wo! 2, Made in Abyss,
The Reflection (despite bad reviews I loved it, great music too), Urara Meirochou, Youjo Senki, Zero Kara Hajimeru Mahou no Sho, Evil or Live (Japanese branch of Chinese studio but is interesting, tiring a bit though), Himouto Umaru-chan R (YES, watch the cancer), Eromanga Sensei, Konohana Kitan,
Owarimonogatari (watch all the other Monogatari series from Bakemonogatari for max enjoyment), Tsurezure Children, UQ Holder! and that's all! Plenty to keep you busy until this crappy season of anime is over and we get some good stuff like Fairy Tail S3!
Damn, forgot to put Mahoutsukai no Yome on the list!;-; Watch it, definitely watch it too! Out of the list, feel free to skip Evil or Live (it's weird because of how it comes from Chinese light novel and it doesn't appeal to that wide an audience), but watch all others
