One major difference is the medium. Manga is a visual medium with panels and illustrations that can directly show the story's events and characters' appearances. A light novel, on the other hand, is mainly text - based, relying on the reader's imagination more for the visual aspects. For example, in Domestic na Kanojo, the manga can vividly depict the complex relationships between the characters through detailed drawings of their expressions and body language. In the light novel, these relationships are described in words, which might allow for a deeper exploration of the characters' inner thoughts.
On the other hand, the light novel may have a dedicated following among readers who love to dive deep into the story through text. Some people might find the light novel more immersive as they can create their own mental images of the characters and settings. However, both the manga and the light novel have a significant fan base, and their popularity can also vary depending on different regions and demographics.
One could be 'Oregairu' which also delves into complex relationships in a school and social setting. Another might be 'Toradora!', as it has elements of relationship development between a boy and a girl.
