Are there differences between Web Novel, Light Novel and Manga of Mushoku Tensei?


I'm currently reading manga and I was thinking to switch to LN or WN so I'm
wonder to what I should read WN or LN.

I'm current in chapter 15 in manga.




As far as I know, the manga follows the same path as the web novel with much
skipped content. I don't know about the light novel but I read somewhere that
there are some differences. And according to Wikipedia
([link](https://en.wikipedia.org/wiki/Mushoku_Tensei#Volume_list)), there
exists a whole volume between WN volumes 6 & 7, that covers Rudeus' adventures
following Eris' departure.
