@Cosmism It’s the subtle things in the manhwa, the little bit of her hair sticking out reflects her emotions: droopy=sad/tired heart: happy lighting bolt: shocked
Yeah I mean that's a fun Easter egg, and it's nice to see the attention to detail but the absence of such is not felt in a novel.
And you have a lot more gained (internal monologues, dramatic irony, even more cute/peppy repartée).
This isn't to say that I always prefer the novel of a manhwa or manga. Certainly not.
For example I tried reading the novel for Omniscient Reader's Viewpoint, and I just couldn't do it because the quality of the prose was too poor. The author is a genius at crafting narratives but lacking in other respects. The same can be said of Solo Leveling. It is works like these that shine through when adapted by masterful storytellers.
Another example of a lackluster novel, well this one is actually rubbish, that has a genuinely fascinating manga is Mushoku Tensei. Well I stopped reading it aeons ago because I aged out of being impressionable enough to like something that gross.
On the other hand, there are occasionally, novels that hold particular spark that are lost in adaptation. For example Eternally Regressing Knight had some of the grittiest, most down to Earth, but still interesting battle descriptions I've seen in a fantasy work written in the past 30 years. The manhwa more than makes up for that with the character design, and humor, but still, lost in adaptation.
While the adaptations are top notch, The Novel's Extra, Got Dropped into A Ghost Story, Still Got to Work, A Villain's Will to Survive, and A Regressor 's Tale of Cultivation are all better in novel format.
