Differences in what "The Simpsons" and "South Park" Call B-Plus

I feel with the receding works of both the Simpsons, who have put in 31 Television Seasons, a few more than any Law and Order, and South Park, who have put in a Generation of Seasons in 20, there are marketed differences in what they'd called B-Plus.

If we had Monday Night instead of Sunday Night Football, we'd have a lot different view of Network TV and Network TV would have stayed reinforced. Knowing from experience, The Simpsons had 2 Pinnacles of Seasons in 1992-1993 and 1994-1995, both still being in Network TV Top 10 History while their rivals barely had a Top 50 of One Season, and I'd still want Lena Durham and her "Girls" to reappear in Springfield, like it was the Vegas Wives conveniently weaving midseries, but, there is no day Hank Azaria or Harry Shearer is not wanting to leave for real this time after there contracts run out.

Where South Park had their best works was 2006-2007 and 2008-2009, not counting the first 2 Seasons, but, I think the difference there was losing episodes to the Writers' Strike in 2007-2008, having to reorder those valuable episodes in 2008-2009, and the rail there was losing subscribers left and right when the economy went downhill, which took away a good audience first run.

We can't deny first run is at a record low. And, to add misery to all this, if we really where to have a B-Plus Simpsons as opposed to No Simpsons, having to write characters in and out, having to write voices in and out, and the rail is, The Simpsons beyond "Who Shot Mr. Burns?" haven't done a multiepisode arc well. Writing in that rare Sideshow Bob/Fat Tony "Treehouse of Horror" would have been great, but, I doubt in the Writer's Room, such an arc would have been appreciated by the National Sponsors they'd have. If we let ourselves go to a garguntuan hyperextension that can't and won't be replaced, it would have been as flowered out as "Family Guy" is after the whole Brian got killed, Brian got replaced, and then, to fan and sponsor anger, Brian got rewritten in, a good chunk of the audience has not been recovered since.
