I've watched and liked

• Monster - good story, good pacing, really enjoyed it.
• Legends of the Galactic Heroes - great worldbuilding, enjoyed the rivalry.
• Death Note - very exciting. Enjoyed the duel between the L and Light.
• Attack On Titan - interesting gimmick, good story, good pacing.
• Psycho Pass S1/S2 - premise of the show is great, but I got bored because the plot seemed to be going in circles
• Texhnolyze - good one, left a big impression on me, Thought about it for days afterwards
• Parasyte - interesting gimmick, solid story, I liked the dynamic between Migi & Shinichi
• Code Geass - I don't like mechs, so it took me a while to start this one, but I was pleasantly surprised by how uncentral to the story the mechs were. The mechs could've been replaced with anything else and it wouldn't have changed the story. I liked the mind games, and scheming from Lelouch.
• Promised Neverland S1 - really good... s2 doesn't exist.
• Shadows House - reskinned promised neverland (in a good way).
• Made in Abyss - great worldbuilding
• Odd Taxi - I liked it a lot when it was running, but it's not something I'd rewatch
• Spice and Wolf
• Alya sometimes hides her feelings in Russian - I actually kind of like this one... Yuki really carries the show.
• Konosuba
• Cowboy Bebop - disliked episodic nature of it, but everything else was solid.
• One Piece

Edit\* crap, this post blew up, thank you all for the suggestions! I'm going to need to organize a list.
