I go with Family Guy. I find the stories in the current episodes to be quite entertaining and good way to look back, especially with them relying less and less on cutaways. South Park, I'm not really a big fan of their political humor, might have to do with me not giving a damn about politics, that and other than the Muhammad episodes, I wasn't really impressed with this season that much. South Park lends themselves more to being outdated by keeping up with current events.
