 If you liked Great Teacher Onizuka |  ...then you might like Kyou kara Ore wa!! |
Both are likeable, manly, rebellious and funny series of the school-comedy-slice of life genre, and both involve delinquents, students, gangs, fights, rivalry, friendship. The main characters in GTO are older than the ones in Kyou Kara Ore Wa, but the style and hilarity level are overall the same. Also, both anime are Studio Pierrot productions and have a rather similar character design.

Both are hilarious with Kyou kara Ore Wa being, probably, the funniest anime I've seen. Though the comedy in Kyou kara ore wa is not sexualized, unlike GTO, it'll still manage to make your sides hurt.

Aesthetically appreciated shows from the 90s that evokes nostalgia. So much meme-worthy elements and out-of-context clips, but also makes for beautiful gifs - across the board great delinquent-comedy that you can turn off your brain to done by Pierrot
the main character is very similar to a what a younger version of Onizuka would be. a lot more gang-fighting than GTO and the might even be better
