Welp, I'm super late, but time for me to post my thoughts on the stuff airing. At least, the stuff I'm following. DO NOTE THAT THIS IS MERELY MY OPINION.
Kidou Senshi Gundam: Tekketsu no Orphans
This was honestly my most anticipated show of the season(aside from Utawarerumono, but that's more because I loved the original's VN so I'm rather biased). I normally don't follow Mecha anime, but I heard Mari Okada was involved, so I got super excited. Was not disappointed. Nice characters, a very real and serious storyline. Awesome OP, good visuals, interesting plot direction. Nice focus on camaraderie and brotherhood. All in all, very worth your time, unless you're super averse to mecha anime.
Utawarerumono: Itsuwari no Kamen
As much as I love this show and this franchise, I cannot in good conscience call it amazing. Pacing-wise, it's rather slow, but also a lot more appropriate for the atmosphere of the show than the adaptation of the first game. Characters are introduced at a realistic, well-paced rate, instead of trying to cram all character introductions into a few episodes. The interactions between Kuon and Haku are a pleasure to watch, and though there are a myriad of bath scenes, these scenes, while still counting as fanservice, do serve a rather important role in displaying the character development. Fans of the first Utawarerumono are likely to enjoy this show, while newcomers to the franchise may also watch it as simply a calming, well-paced Fantasy show with good characters.
Taimadou Gakuen 35 Shiken Shoutai
At first glance, a generic harem. At second glance, still a generic harem. With one of the worst pilot episodes of the season and a boring male protagonist which honestly doesn't stand out at all, the only reason why I haven't dropped this is because the personalities of the girls in the platoon are, while somewhat cliche, also somewhat refreshing. They all fall into typical character archetypes, i.e. Ohtori is the tsundere, Usagi is the unintelligent girl with large breasts, Suginami is the perverted girl that keeps trying ecchi things. However, within these character archetypes, they do show some promising development; Usagi's clumsy exterior hides an amazing strength of will, Suginami's perverse actions stem from a deep-seated curiosity, etc. The world itself is interesting enough to warrant a watch, but what's really good about this show is the antagonist. The extent of their twisted nature is very clearly shown to viewers, and it's a very interesting experience overall. I'd say give the first 3 eps a try, at least. It starts out terrible but gets slightly better. The male protagonist is still extremely boring though.

The premise of this show is extremely generic. The OP video of this show is extremely generic. The characters in this show are somewhat generic. But the sound production of the show is awesome. Most of the characters and their interactions are interactions and traits you will have seen in countless other shows. Some characters do break the mold somewhat, but still roughly fit into the same cookie cutter mould. possibly the most original character would be Do Mon, and he's a side character. But I would watch this show just for the amazing sound effects. The sound production quality on this show is amazing. Close attention is paid even to the most minute details, like passersby in the streets, birds in the sky and chairs being drawn. The BGM used fits the scenes perfectly, and in general the show is a pleasure to listen to. Don't watch it for the story though; you'll be sorely disappointed.
Subete ga F ni naru
Amazing character interactions in this show. The dialogue is very well-written, and the relationship dynamic between the main male lead and the heroine is explored very thoroughly. The mystery itself could be more engaging though. I find myself not really caring about the solution to the mystery, and instead just pay attention to the relationship dynamic between the two. The art style is a bit different from the norm; it utilises less colors and is somewhat more dreary. I feel like this show has a very mature impression; it's a show meant to appeal to a thinking audience who appreciate good storytelling over high entertainment value. It shies away from employing a multitude of the tricks used to appeal to a wider audience, like slapstick/situational humor or fanservice, and instead focuses on delivering meaningful, mature writing carried by its realistic, human character dialogue. Add that it has - in my opinion - the most interesting OP video of the season, and Subete ga F ni naru possibly takes the AotS slot for me. Highly recommended.
