@Serah If I really like a light novel series I'll often read the manga too; it doesn't take that much extra time and it's fun to see the art. But for some novel series I generally like but am less keen on, I've dropped the LN but continued with the manga since it's a lower time commitment. My free time is pretty limited, so I can't read as many series I otherwise might in a vacuum. I'll also follow manga-original series.
For this series, I started with the manga when it started serialization, drawn in by the art. When some time later the LN started serialization, my sense based on what I had read of the manga was that it would probably be one of those series I wouldn't follow both the LN and manga for, so I didn't try it then. But recently, with it going on sale, I did pick up the first volume of the light novel. While I don't hate it, the manga seems like a pretty close adaptation and I think my earlier sense that I wouldn't follow both was right. Usually I think more about missing stuff in an adaptation, but here I think the adaptation might actually be better. I just wish it released a little faster...
