Switching from Nikon to Sony and Dumping my D850

The Nikon D850 has been my go-to camera for a few years now and, though it hasn't ever failed me, it lacks some features that appeal to me.
I've used Sony cameras many many times, but I've never taken the time to EXCLUSIVELY use a Sony for an extended period of time. The little quirks that come with changing systems kept me running back to my Nikon. This time, I'm sticking with it for a while, working through the quirks even when I have an important shoot, and seeing what my final choice will be at the end.
