I use the D850 and have the Tamron 70-200 and love the combination. It is my go to lens for outdoor sports, indoor sports, around the yard bird photography. I don't juse it a lot indoors, but when I do it is during the day and I have had really good results. I use JPG, autoISO, and usually use manual. The results of this combination are really sharp and crisp.
I have a 500 mm prime for more distant outdoor shots as the 200mm just doesn't reach far enough
My experience is the same with my D850 and 70-200mm F/2.8 G2. When researching, I found that the G2 was rated higher than the Nikon version, so for the differential in price, the decision was a no brainer. Based on my experience with the Tamron 70-200mm G2, I bought the Tamron 24-70mm G2. Both G2s has served me well over the years. These two G2s were my go to glass on my Z9 until I was able to afford the Nikon Z versions.
