Imo, I would have to say All In The Family, Mary Tyler Moore Show, and this might be a weird choice but Soap

I think SOAP is a good choice, not a weird one (excluding aliens and possessed babies). And anything Norman Lear, of which you mentioned one.

I would say M*A*S*H. A sitcom set in a war zone guarantees a certain amount of drama mixed with the comedy. And I think the writers, directors, and actors on M*A*S*H handled it very well.
