>>1482446idk if these suggestions will suit your taste exactly and some of them technically have anime adaptations that are either incomplete or diverge from the source material but I think they're really good
if you like berserk's art style you might like witch hat atelier
houseki no kuni has an anime but it only covers the very first part of the manga
the original 1970s devilman and its sequels if you want to read berk's granddad(there are devilman animes but I don't think they're really direct adaptations)
steel ball run(the part of jojo that hasn't been animated yet, it's unrelated to the previous ones so you don't have to watch them)
ajin (the anime follows a different plot from the manga)
BLAME!
duranki(unfinished and only 6 chapters but it was made by kentaro miura and is pretty cool)
hope any of these help
