10 years is a long time so I’ll try to be really selective:

• Kaguya-sama: Love is War - Two tsunderes have fallen for each other, and they’re trying every trick from every book to force the other person to admit it first. This is my favorite romance anime, and my favorite comedy anime as well. The manga is complete, and the anime has adapted just over half of it so far (3 seasons and 1 movie).
• Brave Bang Bravern! - Big gay robots. After all the Gundam and other shows I’ve watched I can’t believe something this silly is my favorite mech anime. It 100% deserves it though. What a sense of humor. This show is complete.
• Mob Psycho 100 - Same author as One Punch Man. A boy with psychic powers questions the value of having such a thing and tries his hardest to become the best person he can be. The same excellent writing quality you experienced with Season 1 of One Punch Man, but with even more incredible animation and a great ending. This show is complete.
