Both are episodic, comedy anime that are directed by shaft staff members (even if in kaguya sama's case its just the director who was a staff member), to me, the biggest difference is how they use the episodic nature to their advantage and zetsubou sensei surely does that much better than kaguya sama while also being a great comedy, i really recommend it if you enjoyed this type of episodic comedy anime.

Both are similar in having a teacher that guides it's class in weird ways that ends up being great for comedic effect, with the one difference that szs goes in a path that allows it to explore much more what it's trying to do and allow for funnier gags (I'd also probably recommend great teacher onizuka as well but since i haven't seen or read it yet i won't say much about it, but i think it's also worth giving a try as well)
