This has traditionally been my favorite type of anime basically ever since I first got into anime, but lately I've just felt like I need it more. Chances are that most things that people would mention in this thread are things I've already seen or tried, or things I already plan on watching — but honestly, just mention them anyways, because they could be useful for someone else, and I'm not opposed to rewatching or prioritizing things.
Still, I might particularly like some more "hidden gem" type recommendations.
Hidamari sketch is the 🐐 of the category imo
I still haven't seen the last season of that, nor the specials. I remember properly starting Hidamari Sketch during lockdown, not just as a soothing ritual for the turbulent time, but also for I was to move to a school dorm later that year, and I was hoping that my first time living alone would be just like the cartoon on my computer screen...
...As you might expect, it really wasn't, honestly it was kinda shit, but God I wish I could be that naïve again.
So yeah, GOAT indeed. Hidamari really is a special little series. Shaft also made Maria Holic and Soremachi, which I also enjoyed a lot, and Pani Poni Dash, which I completed despite not being particularly fond of it.
