Ooo, good to ponder this question from time to time. I'll think or more later but these immediately came to mind:
All-time best movies
-Ghost in the Shell: The story, themes, visual style still gets me.
-Perfect Blue: Great movie about the consequences of chasing fame.
-Haven't rewatched them in ages but Ninja Scroll and Princess Mononoke come to mind, too.
All-time best shows
-Cowboy Bebop is a given but I'd throw Space Dandy into the ring as well, it's an anime that won't take itself seriously and celebrates and makes fun of all the goofiness of the history of anime and its tropes.
-I'll probably be the only one to say but Haibane Renmei. Really made you think about the meaning of life. One of the few anime to make me legit cry at the end.
Recent best movies
-Dragon Ball Super: Broly: The most entertaining DB movie I ever saw in decades. Most beautiful and consistent animation you wish they redid the whole series, DB, DBZ, and DBS in. A very simple story but so effective and not just canonizes Broly but adds a new spin to him. Also a welcome return to Toriyama-san's patent humor as well that DBZ sorta lost along the way - i.e. Bulma and Frieza both having absurd vanity wishes in mind. And of course the spectacle of a Super Saiyan Blue Gogeta.
-Chainsaw Man: The Movie Reze Arc: Again beautiful and consistent animation, amazing action sequences and score, a love story that doesn't have a happy ending, a story with various people and connections...
Recent best shows
-Pluto: I'd hardly call anything a masterpiece but this was. An adaptation of an Astro Boy story arc interpreted for a mature audience, intricately woven storytelling, consistently great animation. It's kind like the different between reading comic book vs. a novel, you can't just passively watch this. It just pulls you in. The parallels of discrimination, the atrocities of war, revenge aren't new or groundbreaking but told very well. Gutwrenching stuff. Urasawa-san honored Tezuka but put his own spin on the tale.
-The Summer Hikaru Died: Another mature story with a mystery and paranormal setting wrapped around themes of identity, friendship, reality vs. lies.
-Dan da dan: Paranormal, aliens, mecha, action, humor, romance, amazing soundtrack, amazing animation from science saru. A real celebration of all things anime in the big picture.
-Shangri-la Frontier: A true love letter to gaming.
-I'll include Frieren, Medalist, My Dress Up Darling, Call of the Night, and Gals Can't Be Kind to Otaku as unexpected hits with me that I took a chance on and really liked.
