While I'm not that old (30), it feels like forever since there's been a wide selection of quality cartoons on TV. Take The Jetsons for instance. The writers' didn't seem to be in a contest to see who could write the dumbest script or teach kids the worst habits. None of the characters scream & yell in an outrageous fashion.
While I can't speak on the 80's episodes, with them not being avalible on Boomerang or DVD, each 60's plot was smart and, more importantly, had comedy that appealed to kids & adults. George was more relatable than probably any other father on TV; always worrying about his wife's & daughter's spending & keeping his job with an overbearing (if, in this case, likeable) boss as well as not being able to understand the newest gadgets. And then of course, there's the second funniest canine in history, Astro. Pure classic.
