There are a number of YouTube videos which call the GX85/GX9 a Fuji X100 alternative, and I kind of agree, and not. The X100 has the unique points of manual shutter speed dial, retro styling, aperture ring, and Fuji's film simulations. The GX85 has none of those things, unless you're using the occasional Panasonic lens with aperture ring like the Pana Leica 15mm f1.7.
Having said that, I use the GX85 in the same way as the X100, as an autofocus aperture priority camera with a fast lens. And for me, I use the GX85 way more than the original X100, due to the ability to change lenses, shoot excellent video, and it works with IBIS and stabilized lenses. It's even smaller than the X100, too.
