Family Guy, Simpsons or South Park?

[DPKdebator]

My personal favorite is The Simpsons, but if we're going based off their current quality South Park is undeniably the best of the three. I like all three of the shows, but in terms of intelligence/satirical value The Simpsons and South Park are above Family Guy. I'd like for The Simpsons to end with the second movie and Family Guy should end soon (maybe with its movie), whereas South Park seems to have some mileage left since its quick production time allows for timely satire of current events while they're still relevant (which is even more of a plus in our ever faster-moving world).
