trash of the count family. it's so good, but the update quite slow. better start with their novel. or solo levelling.
This is the obvious one: Solo Leveling. A bit below ORV in terms of story, but still good for an engaging and good time killer. I haven't finished it or read the novel, I think there might be romance though so meh.
The next one is I woke up as the villain (the title I think is a common trope so the alt title is Na Honja Soseol Song Mangnani) , and I haven't personally read it but I am going to as soon as I finish typing this. I heard that it was a combo of ORV, Trash of the Count's Family, and Solo Leveling.
This brings me to Lout of the Count's family. Really good, although I read the novel and not the manhwa (I heard the manhwa is a bit slower). No romance
I also have survival story of a sword king, although that isn't really like ORV, I just personally liked it (action fantasy, no romance)
Dungeon reset also is a bit like ORV, no romance.
I don't think I recommended the *best* things though, because I personally think ORV is hard to beat. Maybe consider reading the novel if you haven't already? Here's the novel updates link:

It only has a few manhwas for now but all of them are pretty great. My standard being ORV (ITS NO. 1 IN MY LIST) ..I'm still trying to find and read more so you can check back on it from time to time.There are other lists with much more manhwas in it but I've not read them all so I can't guarantee their worth. If you want I can post their link here as well (=・ω・=)
HOPE IT HELPSヾ(❀╹◡╹)ﾉ~

Ok, a bit of an update, I read "I woke up as the villain" or whatever the title was, there's tons of translations, and I highly recommend it if you want something similar!!! There is literally no better description besides being a combo of solo leveling, trash/lout of the Count's family, and ORV.
At first, the art style doesn't seem that good, but it's only because the artist only put flat colors with the most basic of shading, in reality the line work/anatomy is on par with the others. The difference is the lack of flashy effects, but it's easy to get used to. I might be biased right now since I just finished reading it and the novelty hasn't worn off yet, but it's really good, check it out~
