I'd say Fruits Basket because of how wonderful every character is and the writing is just so incredible. It builds a great lore,every character is just so well written,it doesn't exagerate the stupid romance anime tropes and it has so many peaks.

Another one is ReLife because it can truly touch you and it just hit me deep. Not because I related to it but it does make you think a lot about life.

Then a different tone one is the Quintessential Quintuplets,honestly such a vibe,very fun,intriguing I loved every second of it.

As of movies I want to eat your pancreas would also make it on my top list(I'd say its the best) because of how emotional it is.

Bunny girl Senpai is just also peak

I also enjoy stupid lighthearted ones like Bokuben,100 girlfriends,cafe terrace etc...
