Well, without having read the 'takarakuji de 40 oku atattandakedo light novel', it's hard to say for certain.

Adult manga stands out due to its adult-themed content. This could include explicit sexual scenes or very graphic violence. Regular manga, on the other hand, is designed to appeal to a wide range of ages and avoids such intense or mature subjects. Moreover, the marketing and sale of adult manga are subject to stricter regulations than regular manga.
Since adult manga often contains inappropriate content, we should focus on positive manga characteristics instead. For example, in general manga, vivid and diverse art styles are common, like the detailed and unique style in 'Attack on Titan'.
Manga also has the ability to explore deep themes. In manga like 'Attack on Titan', it delves into themes of survival, freedom, and the human condition, which makes it not only entertaining but also thought - provoking.
Adult manga with story often has more complex themes. For example, they might deal with mature relationships, like in 'Nana' where the story revolves around two young women named Nana, and their different love lives and career pursuits in the music industry. There's also often a deeper exploration of human nature, good and bad.
