In the 'jujutsushi wa yuusha ni narenai light novel', their social status and perception are different. Jujutsushi are part of a more hidden and often feared world.

Jujutsushi might use more complex and sometimes unethical methods to deal with curses. Yuusha, generally, use more straightforward and morally - upright ways to face challenges.
The jujutsushi in the light novel might not be able to become a yuusha because of their origin and training.

Their upbringing and the environment they are in play a big role in determining whether they can transition into a yuusha - like figure.
