Married .. with Children, without a doubt. But, it's kind of hard for me to compare the two shows. Their contents are too different. Older shows in general had more nudity and sex and less violence, where it's completely vice- versa when compared to modern shows. Also, Married .. with Children was allowed to make stereotypical jokes (i.e. the French and fat women) and still be rated PG. War at Home has to be TV-14 because of all the drug references and racist jokes and such. So, it really depends on what type of TV show you like better. (I guess I got the FCC involved into this). But here is how I review old shows to modern shows based on what I've seen.
More: Nudity, sexual puns and references; stereotypical jokes.
Less: Violence, blood, language, racist material, drugs. (They also didn't have to rely as much on current pop culture/trends where no one will understand it in five to ten years)
(Much) More: Violence, blood, language, racist material, drugs (as well as relying too much on what's happening at the same time as the production. They need some more timeless material.)
Less: Nudity, sexual puns and references; stereotypical jokes. You should know the difference between "racial" and "stereotypical." For instance, Al thinks all French people are bad, where Dave thinks all people from the middle east are terrorists. Al isn't saying anything negative about the French (except that he doesn't like them), but Dave is (and if you take into consideration that he's Jewish could be a little stereotypical.)
Okay, kind of got off- topic there. But I still stand by my point that Married ... with Children is far better than War at Home could ever be.
