I wasn't looking for a replacement body, I wanted another smaller body to carry around more than I do now. Mine will be the Z6 as it will be better at low light than the Z7. I like to low light performance. The D4 can take shots in near darkness. If you look at my other ISO test, the Z7 sensor is darn good. I think the Z6, with the larger photosites, will be just as fantastic. Pixels really don't matter to me. I have printed 5 ft x 7ft images from the D4, it's what Nikon dos with them that matters.
I was leaning toward the fuji X-T3, but in playing with the T1 and T2, the buttons were a bit small for me. It's cold here in winder, and with glove liners, I didn't think it would work for me. When the Nikon came out, and I got to handle it, I fell in love. If one is looking to have a mirrorless as an addition, I recommend it.
As a replacement, I would replace a D800 with it if I was hiking with it all day, and I don't need what a DSLR can do. I like shooting stars, so the Z6 would be great (should be) great at that. It's all personal preference.
Photography: 100 percent art, 100 percent technical. It takes a photographer to blend them into an image.
Film: That tangible image that you can see and hold.
