Oh, I like it so much. Solo Levelling is good, but in my sincere opinion this manhwa is better. Incredible art, sassy protagonist, interisting game mechanics (unfortunately, there are description of titles and abilities, but it was not that tiresome to read). There are SO MANY fights, it isn't tiring, you feel in rush to get to the goal like the protagonist (and at the same time you wonder about what's happening to the world in which he is as well), and besides the suspense there are those heart-warming/fun moments to smile a bit amidst the "cold-hearted jungle" of survival of the fittest.
If you have read many isekai comics and want something similar but not too generic/repetitive, then "Ranker who lives a second time" is FOR SURE a good read to add in your list, buddy.
[I don't know about the novel though. There are some friends of mine who say it's good, others said it's average or that it became boring afterwards, but who knows?]
