This pretty much sums mine up. I could expand the list probably into the hundreds, but I’ll leave it at this.

-he-man
-Thundercats (my all time fave has a child)
-silverhawks
-bravestarr
-the real ghostbusters
-C.O.P.S.
-transformers
-GO Bots
-TMNT
-X-men
Now we’re talking. You forgot Blue Falcon though.
It was called “Groovy Ghoulies” Groovie Goolies - Wikipedia
I mentioned it earlier.
Leiji Matsumoto’s characters are gorgeous.
Blue Racer
Batfink
Lippy the Lion and Hardy Har Har
Fractured Fairy Tales
George of the Jungle
Not necessarily in that order; and I think that’s probably enough…
When I was three and four, my favourite cartoon was Tetsujin, released in the U.S. as Gigantor. I spoke Japanese as a child, and I remember I had an inflatable Tetsujin toy. I never watched the U.S. release.
Cartoons seemed to change every year, so I can’t remember specific line-ups. I do remember watching The Bugs Bunny/Road Runner Hour. Good times. Others were The Groovy Goolies, Mighty Mightor, The Wacky Races, Speed Racer, Punkin Puss & Mushmouse, Hong Kong Phooey, King Kong, Jonny Quest, and many others.
Still, when I think of those times, I remember drawing runways on teletype paper dad brought home from work, and playing with a blue Matchbox jet while watching Skyhawks. Dad was a pilot and was a flight service specialist in the FAA, and mom was an aviation secretary. There were cartoons that lasted longer, and ones that were ichiban when they were on. But I always remember the planes first.
When I was a kid, you saw cartoons at either the theater or on Disney (the program, not the channel). I grew up with Mel Blanc doing Bugs, Daffy, Foghorn, etc.; Woody Woodpecker, Roadrunner, Tom & Jerry, Popeye and the Disney stable of characters. Wonderful animation, unlike all the stop action cartoons that came later.
A shout-out for:
Johnny Socko And His Flying Robot!
Gandy Goose. I’m still looking for “Mother Goose Nightmare”.
Well, I popped in to mention some of yours. They were part of the “One Saturday Morning” lineup that Disney did on ABC. A big part of my kids’ childhood: my daughter and her friends sing the PepperAnn theme in their college hallways. (Are you 19 or 20 now?)
I can still get my kids and college students nostalgic by singing the (brilliant-written) theme song: "Five hours of summer / once a week… " What a great way to sum up sitting in front of the TV with a bowl of sugary cereal, watching cartoons while the grownups are sleeping in.
Heck, I even took my son to see the “Recess” movie, in a theater.
Oh, found out he’s in a Facebook group: “RECESS was the BEST show on TV ever!”
A lot of my favorites were already mentioned but I have a lot more. I was born in 1989 so cartoons became a way of life for me in the 90’s and 00’s. I’ll just point out the superhero shows that maybe weren’t mentioned yet:
Batman: the Animated Series
Batman Beyond
Superman
X-Men
X-Men Evolution
Static Shock
Gargoyles
Spiderman
Powerpuff Girls
Thank og for Netflix. My niece thinks the Rugrats are the best thing ever, never mind that Tommy is as old as her aunt.
Warner Brothers + Looney Tunes + Merry Melodies = #1 
Why does everyone keep calling it “The Roadrunner”? He wasn’t the star, he only made cameo appearances. Wile E Coyote was my favorite cartoon, if that wasn’t already obvious.
The rest of the Looney Tunes and Rocky & Bullwinkle are my other favorites.
Transformers (original and Beast Wars)
TMNT
Ronin Warriors
Rugrats
Gargoyles
X-Men: The Animated Series
Batman the Animated Series
King Arthur and the Knights of Justice (don’t judge me)
Also, not cartoons, but lots of Power Rangers.
Jonny Quest
The Herculoids
Space Ghost
Superman
all these and more favorites.
But hard to compete with The Three Stooges and The Little Rascals.
Hong Kong Phooey (Loved his theme song: “Hong Kong Phooey! Number one super guy!
Hong Kong Phooey! Quicker than the human eye!” Ah…)
I also remember a show called Mission: Magic way back when.
And Funky Phantom. And Wacky Racers. And lots of the ones mentioned previously.
The WWII Warner Brothers cartoon “Herr Meets Hare” had two firsts.
It was the first Bugs Bunny cartoon to feature the gag of Bugs "taking the wrong turn at Albuquerqe. "
And it also featured the fat horse and Bugs as Brundhilde, with Hermann Goering as the smitten one.
So both gags got reused.
I agree, Warner Bro. is first.
