To some extent I think Louie set the precedent there, as CK was given complete creative control. Comedians were asking for "the Louis deal". Glover (and Ansari) seemed to get it, and both had the sense to hire other talented people. Louie (the show) suffers from its self-indulgence to the point it can't be rated that highly, where Atlanta maybe mostly avoids that fate.
I would say the marvel tv series so far have been pretty solid. Even if you don’t like them because you have an allergic reaction to marvel, their execution has been really good.
If we must talk of THE BEST, then season 1 of American gods on StarZ was the best season of television I’ve ever seen. Mostly all written by Bryan fuller and Michael Greene. Not entirely. How do we weigh this? Hard to say, but man did that show crash and burn when they left.
I saw the first season of American Gods on Starz as well. It did not motivate me to watch the second season. That same year, though, we had The Good Place (showrunner), Better Call Saul (showrunner), The Deuce (showrunner), The Leftovers (showrunner), Maisel (showrunner), and Legion (showrunner). I think the model acquits itself nicely.
