Some nice, smooth, consistent quality. Better Call Saul was in my opinion pretty consistent. Single season anime is almost always consistent, like My Dress-Up Darling or Terror in Resonance.
Not dragging on longer than the series needs to seems to be a key point.
iirc, the showrunner, Dan Harmon, had some allegations against him and they ditched him. I'm unsure of the reality of the situation or what the allegations even were, but he came back for the last season.
