The LN is almost always going to be the "canon" version that a manga or anime is based off of. You can essentially think of the WN as a sort of rough or first draft, and the LN as the final draft that has some changes and more detail. As
@Kisato said, while there are some changes and more detail in the LN, the main story beats are the same or similar enough. So it doesn't really matter which version you read if you're also going to read the manga.
The WN hasn't finished translating yet, but it is very close, about 10 chapters left. Meanwhile, the LN has no fan translation aside from the first volume. It is however being officially translated and published in English by YenPress. There's only 3 volumes so far, with the 4th coming out in December, so it's currently behind the manga. If you're fine with waiting and would rather read the "official canon" version, then stick to the LN. If you can't wait and just want to know the general story for now, then you should definitely read the WN. If you're going to read both, you should read the WN first then the LN.
