Both shows include an overpowered protagonist who consistently outplays and beats monsters with ease following a training arc. OPM is much more comedic, SL is not so much.

Both are very wacky action/comedies that use unique power systems. The two shows have very unique and wild/colourful art styles that mean if you liked one, you have a good shot at liking the other a ton.

Shinmai Maou no Testament
|
Both have a main girl with red hair, both involve contracts/devils. Both have action/comedy mixed in with extreme ecchi, if you liked DxD you'll like Testament (and vice-versa). DxD has a more underdog protagonist to begin with whereas Testament's is shown to be more experienced in his verse.

Dakara Boku wa, H ga Dekinai.

Both have a main girl with red hair, and both involve contracts. The "Shinigami" in So, I can't play H! is very much like the devils in DxD. They both involve a lot of comedy and include a naturally pervy main character who despite being a degenerate is genuinely kind at times and shown to be compassionate.

Girlfriend, Girlfriend is a comedy harem set in a school like Quintessential Quintuplets. It's fairly underrated/over-hated and can provide some good laughs if you enjoyed the former.

This is a lesser known, spin-off where Minami (a fan favourite) is the star! A lot of fun, quite short and a must-read for fans of the source material. (It's an AU that's not canon for the most part, mind you).
