Looking through the shows I have enjoyed the most in the past couple years here are some that I don’t see on your list:

• Bocchi the Rock
• Eminence in Shadow
• Lycoris Recoil
• Heavenly Delusion
• Oshi no Ko

Also, it might be (quite) a bit older, but if you really feel like you need something dripping with melancholy, I would recommend Mushi-shi.

Cyberpunk: Edgerunners is solid and Chainsaw Man is enjoyable, if a tad overhyped.

I see that you’ve got Konosuba on your list but not the Megumin prequel so I’d suggest Konosuba: An Explosion on this Wonderful World

Chainsaw Man

To Your Eternity

Attack on Titan S3 and Final Season Part 1

Bocchi the Rock

Vinland Saga

The Garden of Words

Ping Pong the Animation

Rose of Versailles

The Night is Short, Walk on Girl

Hunter x Hunter (2011)

Re:zero Frozen Bond OVA

You’ve seen a boatload of anime, but you haven’t seen the classic movie Akira or the tv series Shingeki no Bahamut: GENESIS.

For something relatively new there is Jujutsu Kaisen.

Here’s some underrated ones that I didn’t see already posted.

1. Ya Boy Kongming - the most ridiculous plot I have seen and PA works made it work.
2. Akiba Maid war - I swear PA Works are cooking something
3. Summertime Render - Amazing time traveling thriller.
4. Blue Lock - HYPE!HYPE!HYPE!
5. Call of the night - anime which asks “can you watch an anime just for the vibes”
6. Tomodachi Game - Anime Squid game
7. Vivy fluorite eye’s song - Idol Waifu Terminator written by Re zero creator
8. 86 - A very gripping mecha genre anime which are not classic bipedal robots.
9. ODDTAXI - Even with a simple art style, this one goes hard on a mystery thriller.

I noticed you haven’t watched Zombie Land Saga yet.

I haven’t watched anime in years but looking at my anilist apparently I thought highly of concrete revolutio. I don’t remember a single thing about it but I gave it a 9 lol so try that out.

Sleepy Princess in the Demon Castle is a fun and cute show if you’re looking for something like that.
