Z9, R8, A7S. Pick one. Which camera is in last place?
It would help if you correctly categorized cameras. As I've written, A1, R3, Z9 is a tight race, and there is no "wrong" choice. Having used them all, I prefer the Z9 except for one thing (which has now been solved by a third party).
Beyond that top level, it gets more difficult to categorize cameras, though I suspect the R5 and Z8 will end up being easily compared, and I don't think that comparison will end with the R5 "winning".
Unless you decide to buy new top-end cameras every year, you're going to find whatever you buy isn't always at the top of the heap.
