Manga

DICE, Soul Cartel, Tower of God and The Gamer are great
Killing Stalking is great too buuuut..... Ummmmm. It's not for everyone, give it a try
Another good webcomic is Cherry boy, That Girl. It's romance and comedy, i really liked it

As for manga, you need to read Oshimi Shuzo's mangas (Inside Mari, Happiness, A trail of blood)
Beastars is great too and it's getting an anime this october. If you're into soft Girls love and action, maybe check Himenospia
Do you know I am a Hero? You should also check Ressentiment, it's from the same author, but it's an older manga. It's one of my favs
Dr. Stone and Sun-ken Rock are great too
