I kinda feel like I've already seen every big/well known show that I'd be interested in, and even plenty of obscure things that still regularly show up on various top 10 underrated anime lists. I'd also prefer suggestions from earlier than 2015, since that's when I started following shows seasonally, and I feel I'm pretty well caught up. Basically, I'm looking for shows that either slipped under the radar for one reason or another, or shows with flaws that keep them from being universally recommended but still have enough redeeming values to be worth watching.
I strongly doubt you've seen everything worthwhile, considering the wealth of anime that's been produced over the decades. Even as far as big or well known works go, I imagine there's a number of older anime that you haven't seen yet.
Mostly, I'm looking for two different kinds of shows.
First, a good, decently fast paced (so no 100+ episode shounens) action show with a focus on fast and interesting visuals. Some examples of shows like that that I feel are very rarely mentioned:
Yozakura Quarter (the 2013 one)
While they don't all have the same approach to animation as the shows you listed, some action anime which don't drag and which have eye-catching visuals I would recommend are:
Blue Exorcist movie
Boruto: Naruto the Movie
Dirty Pair (especially the movie Project Eden)
Doraemon: Nobita's Dinosaur 2006
Fullmetal Alchemist 2003
Fullmetal Alchemist: The Sacred Star of Milos
Fuse: Memoirs of a Huntress
Hunter X Hunter 1999
Jojo's Bizarre Adventure OVA 1993
Kara no Kyoukai Movie 5: Paradox Spiral
One Piece Movie 6
One Piece Film Z
You Are Umasou
Secondly, something with a good and interesting world, where it feels more like the world and its mysteries are the main draw, as opposed to characters or the overall plot, if possible with the presentation of said world being as unique or imaginative as possible, or even just something with unique and otherworldly visuals. Some examples I've seen would be:
Several Space Dandy episodes (like 21, 18, 9)
Shin Sekai Yori
For this kind of work, I would recommend the following (including several anthologies):
Flowers of Evil
Genius Party and Genius Party Beyond
Kagewani (S1 only)
Patlabor Movies 1 and 2
Sengoku Collection (certain episodes)
Space Battleship Yamato 2199
Urusei Yatsura Movie 2: Beautiful Dreamer
Really though, I'm open to any suggestions that have a strong and distinct visual or animation style. It seems most anime reviews focus much more on the story/character side of things than on the visuals/overall execution, which can make finding interesting shows to watch rather difficult for me, as I much prefer the latter. For reference of what I've already seen, here's my MyAnimeList, although it might not be 100% up to date: https://myanimelist.net/animelist/Pellaidh.
There are a number of people here who do care about visuals (as well as plenty of people who don't, of course), so you should be able to find a couple sympathetic souls here. I used your MAL to draw my recommendations from the overlap of what I have seen and what you have not according to your list.
