Honestly, the webtoon's way better than the novel. First of all, because of the illustrations, and lastly because I think the novel lacks of good writing. I mean SL is not really good when it comes to writing for a lot of reasons. But the manhwa was better handled by the writer compared to the novel, which seemed a little chaotic and botched. You will probably lose some secondary details but from my perspective it's not a problem in SL's case.
