Slice of Life: Slow Loop hands down. I picked it up late, but I'm glad I did. Like I posted in the thread (which I've never bothered to keep posting in) with some edits:
It is a really intelligent mix of "cute girls doing cute things" on the surface level, and uses that as the comedy relief for what type of series it really is, an exploration of grief, loss, and the corresponding recovery...But there's a ton of introspection and emotional exploration packed into these episodes.
It's up there with Yuru Camp. Less serene, but deeper emotionally. It will be in my top 3.

Hakozume I dropped.

I think a lot of people are sleeping on Fantasy Bishoujo Juniku Ojisan to because all they see is another isekai in a season full of trash isekai. It's top-tier parody isekai. Different flavor of degeneracy from KonoSuba, and with an equally talented cast. We're going to get more parody isekai in the next few seasons coming up. Equally great ones.
