The X-H handles nice, but as a still (amateur) photographer, the X-Ts are where it's at. Having separate, physical controls for exposure compensation, speed, ISO, and aperture is a delight. The tilting screen on the X-T line is also a better fit for still photography than the articulated one on the X-H lines. Here's hoping they keep it.
I have an X-T3 now, I'm waiting for the X-T5. It should come out in a few months, and cost a bit less than the X-H. The main advantages should be the 40 MP sensor (vs 26) and sensor-based image stabilization (introduced in the X-T4). They also offer a pixel-combining mode now that shifts the sensor very small, precise amounts and then combines images to increase resolution up to 4x in the final result. You need a tripod and some time, but I'm looking forward to playing with it.
It's hard to explain exactly how, but the color rendition straight out of the camera on Fuji kit is also second to none. Other posters commenting on RAW files are right, though - they're a pain because of the non-standard sensor. Only Fuji's terrible software and commercial offerings like Lightroom do a decent job. Darktable, for example, doesn't. I stopped shooting RAW partly for this reason, but also because the JPG engine on Fuji kit is outstanding. It makes the best JPGs straight out of the camera I've ever seen.
The APS-C sensor size across the entire line also means that high-quality glass is a bit more affordable, smaller, and lighter than some of the competition.
I guess I became a huge Fuji fanboy along the way.
