It's really hard to say anime because a lot of anime that I love I'll finish and then seek out the manga, so it'd be more of a favorite manga than a favorite anime. I'm gonna go top 4 anime and top 6 manga tho lol.
anime:
Osomatsu-san
Arakawa under the Bridge
Daily Lives of High School Boys
Uchouten Kazoku
manga:
Gekkan Shoujo Nozaki-kun
Mob Psycho 100
JoJo's Bizarre Adventure: Steel Ball Run
Takane to Hana
One Punch Man
Noragami
In general I tend to prefer comedy and romance, but there's obviously things I love that deviate from that.
If I had to just flat out give recommendations, I'd most strongly recommend Mob Psycho 100, Gekkan Shoujo Nozaki-kun, and Uchouten Kazoku from my lists. Then I'd also like to second pychi's recommendation of Tatami Galaxy because I really enjoyed it!
