Dorohedoro is the best manga I've ever read. Writing(characterization, plotting, worldbuilding and pacing) is phenomenal.
Guilty Shounen pleasure is Eyeshield 21. Reread it a lot. Favorite gag manga is Gintama, though it does lul in some parts(due to action, main storyline).
I don't have a favorite shoujo. W Juliet would be the most complete one. Funny and wonderfully romantic.
Early Skipbeat was also satisfying, but now its too immature and boring. Boys Over Flowers is wild, but problematic af.
