Funny, at the time, I thought Seinfeld was better (and more innovative) than either of those. Married With Children was mostly just about being as crass as possible, which has been topped significantly since by shows like South Park and Always Sunny, which broadened their shows to not make it just about “how trashy can we get” and Third Rock… eh. Mostly just weird for weirdness’ sake.
Seinfeld had some pretty decent ideas for a sitcom like the episode taking place entirely while waiting in the restaurant entrance for Chinese take-out or the episode which is entirely set in a parking garage. There just wasn’t TV like that back then.
