IMO it boils down to remembering that cameras are just "tools". Does a SnapOn tool perform better than a Craftsman? Both do the same job with excellent results. It seems that there are folks out there that must have the latest gear regardless of price. I'm not one of those. As we know about technology, it will always be rapidly changing and those changes are aimed at our pocketbooks. Many great products to choose from, and many are so close in performance that making a choice is often a challenge. Best to read reviews and customer comments and then decide for one's self what is best for them based on what it will be used for (wildlife,landscape etc). Like a pro mentioned recently "bodies come and go, but really good glass is where it's at". My current D850 will have to suffice for a while since I've invested more in high glass rather than another body that will be replaced soon.
