I personally really like comedy yuri so my fav ones are: Yuru Yuri, Kiniro Mosaic and Yuyushiki. I also would add New Game! and Inugami-san to Nekoyama-san
The classics for the Girls and Guns genre: Canaan, Noir (El Cazador De La Bruja and Madlax to complete the trilogy), the most recent one is Lycoris Recoil, a less recent one is Akuma No Riddle
Original anime: Shoujo Kageki Revue Starlight, Princess Principal, Izetta: The Last Witch, Kill la Kill
Idol anime: Love Live! (I'm an original love liver so my favs are LL and LLS only)
