Pls recommend manga with awesome art-style and story, not restricted to any genre. Any hidden gems. I really liked dorohedoro, summer time renderer, koe no katachi, nana to kaoru, donten prism solar car and eye shield 21, to name a few

You'll have to wait a bit for the amazing art, but Tower of God has some of the best I've ever seen. The story is amazing, with plot twits that will throw you for a twist, and amazing world building. I've never read any of the manga on your list except Dorohedoro, but I think it's worth a go any way (oh and read the manga not watch the anime, they kinda screwed it up a lot).

And you've probably read it, but Toukyou Ghoul gives all your requirements as well (manga not anime as well here)

Kuberadoesn't have as amazing art (although very good) but the story kills.

The Ember Knight Also has all your requirements, plus some twists, and a very unusual MC.

Gilgamesh Is by the same author as TEK and has the best drawn fight scenes I may have ever seen. I dont' know if it matters to you, but it also has the best female characters and fight scenes I've ever seen. As for the plot, the near ending has very mixed opinions, but the rest is great.

Omniscient Reader Also has a great plot and art. Oh, and it doesn't follow the usual isekai genre, if that bothers you
