I recently bought a set of Haida ND filters, and I'm very pleased with the quality. Very little color cast, just a tiny shift to yellow, but much less than I've seen in sample images that used Lee and Hoya.
I opted for screw-on filters rather than square for two reasons: I've not been able to stack square filters because of light leaking in between them creating flares and smudges – and I find it inconvenient with having to carry the adapter rings and filter holders in addition to the larger filters. My set of three Haida filters screw together into a convenient puck that's pocketable.
Here are two photos taken with Haida filters, and an X-E2:

I have a set of step-up rings to use the filters on lenses with smaller diameters.
The Haida screw-on filters are available in sizes up to 82mm, so they should work with the XF 10-24mm. There's also a 100mm and 150mm square series.
