Must watch cartoons?

I'm relatively new to western animation. What are some must watch here?

Few cartoons I have seen:

-Avatar: The Last Airbender
-Legend of Korra
-Gravity Falls
-Steven Universe
-Daria
-Clone High
-Clerks: The Animated Series
-Old Spongebob
-Rick and Morty

I'm aware I'm missing a ton of possible things I could be watching so would anyone care to fill in this gap with some suggestions or some sort of comprehensive guide?

-Adventure Time
-Gumball
-Regular Show
-My Little Pony
-Samurai Jack
-Foster’s Home
-The Loud House
-Young Justice

-Dan Vs
-Lastman

Ventures Brothers is one of the best cartoons out there, definitely give it a watch. First season isn't great but it picks up a lot by season 2. Some other good ones off the top of my head:
Kim Possible
Ugly Americans
The Boondocks
Justice League Unlimited
Batman TAS
Batman Beyond
Frisky dingo

Moral Orel
Prince of Egypt
ReBoot
Beast Wars
Thief and the Cobbler (Recobbled cut)
Samurai Jack
Sym Bionic Titan

Why is nobody posting the obvious answer of the Simpsons (seasons 2-9 for best viewing experience) while seasons 1 is good I wouldn't recommend starting there.

some of my favs are:
>Over the Garden Wall
>Samurai Jack
>Duckman
>Batman: the Animated Series
>Space Ghost Coast to Coast
>Xavier: Renegade Angel (not 2d, but amazing)

If you like variety shows, Kablam! is also a great showcase of creative alternative animation
