@Rayster "ust hoping that Japanese mangakas/authors would step up their game and not be complacent" There's still decent and good stuff to find. For example, in case of "modern isekai", "New Gate" was decent, and I liked "Ride On King" due to how crazy it was. Also there's "Handyman Saitou in Another World", "Realist Maou". From non-isekai... "Sousou no Frieren" seems to be VERY good, there are also had things like "Somali to Mori", "Soil", "Slime Life", "Mieruko-chan", "Kitsune Spirit", "Houseki no Kuni", "Dainana Joshikai Houkou", "Wakusei Closet".
The real treat on this list, however, is Sousous no Freiren. So far this seems to be a real gem and quality of the rest varies.
Meanwhile, after going through my list, I found bunch of low-tier Manhwas. For example "Solo Login".
