Not going to lie OP, if you have a high standard, you'll be disappointed by most of the things mentioned here.
For manhwa, I only have 3 recommendation:
Omniscient Reader's Viewpoint which you are already reading. Keep at it, it never gets boring.
SSS-Class Suicide Hunter - Name sounds terrible. But story is very unique. Characters are interesting and mostly all villains have strong backbone.
Tomb Raider King - Inferior to both but MC is quite different. He doesn't act edgy like a lot of other manhwa MC. Mostly uses his brain to get stronger.
That is unfortunately it for manhwas. All those should have more than 100+ chapters and Tomb Raider King should have even more than that. For manhuas, I have zero recommendations because most of them are bad. Author is just gives up on the story half way through or the artstyle of the manhua is painfully bad.
I have a lot for manga, drop a reply I will reply with manga list when I have time
