That's a pretty tough question, since those are pretty broad ass categories, and some of my favourites are like, still ongoing but not as good as they used to be. I guess I'll just list them in no particular order (also, I'm not considering anime as part of the list, just because that's even way more broad)

Animated:
The Simpsons (though its quality has drifted significantly into basically an entirely different kind of show, those seasons running through most of the 90s and early 00s are pure gold)

American Dad (somehow only managed to get better and funnier and the seasons went on. Like the Benjamin Button of TV shows)

Moonbeam City (incredibly underrated both from a humour and artstyle/animation angle. Just a top tier adult cartoon)

Futurama (also solid gold and quotable as fuck. Haven't watched any of the new season though since the time loop finale)

Amphibia (by far the show I was most hyped about while it was airing, especially in the last number of years)

Not Animated:
Chernobyl (I dunno why, but I just keep coming back to rewatch it sometimes)

One Piece (yes I like the netflix version more than the anime, fucking fight me)

The Purge (I actually quite like that series of movies and the short lived TV series was especially pretty cool for having a season that mostly takes place between Purge Nights and what that's like.)

The Twilight Zone (specifically the one from the 60s. Just something charming about it)

The Wire (I suppose? I recently watched through it for the first time and it's quite good)
