-------------------------------------------------------------------------------------------------------------------------------------------------------------------

The only ones which I really watch nowadays are Adventure Time, The Simpsons and American Dad. All of them are great, though. Probably in that order are my preferred ones.

Other ones I enjoyed were Recess, Hey Arnold, Fairly Odd Parents, and Dexter's Lab. 

Ed, Edd, n Eddy was my favorite growing up.
Spongebob as well.

I like most of the cartoons you listed. Add to that list: Adventure Time and Steven Universe. Oh and the Powerpuff Girls and Dexter.

I like a lot more than those I mentioned but it would be boring to list them all.

Spongebob Squarepants
Avatar: The last Airbender
Oggy and the Cockroaches
The Simpsons
