looney toons is classic, i actually find it sad that no one watches them anymore. they still played them on TV when i was a kid, but probably not anymore. same with flintstones, jetsons, tom and jerry.
best (english) cartoons for kids imo:
robotech (this counts since it’s substantially diff from macross/southcross/mospeda), transformers, he-man, gi-joe, batman, avatar, ducktales, tail spin, tiny toons, animaniacs, x-men, muppet babies, thundercats, looney toons, tom jerry, carmen san diego, scooby doo. rugrats, ferb, teen titans, and hey arnold i’ve heard are good but after my time.
