I'd take both because I always take a backup camera! I have the D500, a Nikon 200-500 and Nikon 80-400, and a D800 and a Z7. In Yellowstone I use the D500 and the 200-500 about 95% of the time for animals and either the D800 or Z7 for landscapes, which I don't take a lot of since I'm usually there for the animals.
I kept either a 24-70 or 70-200 on the 850 and a long one on the 500.
