So if you have Nikon lenses, generally, it is a D850 and Z7
But there are use cases that could lead to a different answer. For example, if your use case is sports and/or action, then it is a probably a D6.
If you don't have Nikon lenses or your investment in Nikon lenses is very minimal, then in my view you need to evaluate the alternative systems and determine which lens lineup best meets your needs.
Then the answer might be the legacy Nikon or Canon systems. Or it might be the new mirrorless system and you might be making that decision based on what is available today or in the near future - for example, based on the Nikon lens roadmap.
Based on the above, unless you are already invested in Sony, I find it difficult to recommend Sony. But if you already invested in Sony, then I wholeheartedly recommend Sony.
This is because in the long run I don't believe that Sony will be competitive with Canon or Nikon on lenses. You still might like Sony because of the cameras - but I think that picking the camera first is backwards for the simple reason that your decision could change every two years, something I could not imagine happening if you base your decision on lenses.
As for mirrorless, even the R5 has compromises and I am sure the Z6s and Z7s will have compromises too. While these will all be great mirrorless bodies, I think mirrorless will really fly past in 4 years with the mark 2 bodies from Nikon and Canon that fix things like EVF lag and battery performance.
