I agree with @Ohayotaku. Clannad is quite a bit more dramatic, especially the second season "After Story".
If you're looking for something lighter and similar to Takagi-San then maybe something like Tonari no Seki-kun, or I thought Acchi Kocchi was pretty fun. Maybe also stuff like Nichijou or Azumanga Daioh.
Hope this helps..
Is it worth watching will depend on your own preferences. If you’re looking for something similar to Takagi-san, Clannad isn’t a good fit because it is much heavier. Kaguya-Sama: Love is War would be a better match. For something comparable to Clannad, there’s Rascal Does not Dream of Bunnygirl-senpai. Melancholy of Haruhi Suzimiya splits the difference.
I'm kinda proud of this one. One of my friends commissioned me to make this character for him. I wasn't sure about doing commission work since I only JUST got back into drawing after at least 5 years of not doing it seriously. But yeah hope y'all like it. It was inspired by the Jack Frosts from the Persona games and Craig Tucker from South Park.
