Pretty sure I'm like the only Sayonara, Zetsubou-Sensei "fan" left alive at this point.

I actualy like all the Kumeta-verse anime, SZS, Joshiraku and specialy Kakushigoto. The latter is probably the best and most acessible in general, but you wouldn't recognize these all being the same mangaka unless by the obvious artstyle. Just seeing Kakushigoto's MC roleplay as Zetsubou sensei was my own weeb nostalgia lol.

Its obviously dated now, specialy SZS, one of the gags is literally a girl Nokia phone texting. But it is some very cynical and based commentary on Japanese society, obviously exaggerated, but any weeb thinking Japan is dream land would be de-converted pretty quickly after watching it.

But it is also extremely dialogue heavy so if you can't enjoy reading subs then its just meh, art is also mid, though if you understand why the choices were made it makes sense and its kind of charming. Its unfortunate but I still think its a personal gem.
