@kitsunesoba - Thanks for the offer, but I think it sounds like overkill? Creating this list was more of a data gathering curiosity... with only two proven viable displays actually available for sale, and most looong discontinued, the number of people who would benefit from that kind of filtering is going to be very small... and with this few of displays, over nearly a decade of 5K panel existence, I'm not sure there is any benefit to change tracking, forking, etc? A concise post here in the forum, with all of the data here in the forum co-located with the discussion of that data, ensures its existence for the people who need it most.
In truth, for most 27" 5K monitor buyers, the decision flowchart is actually quite simple:
1) Did I find something locally / cheap / used?
Yes -> Go with that one.
2) Am I handy with electronics?
Yes -> 5K iMac conversion
3) Am I willing to gamble?
Yes -> Kuycon G27X
4) Am I willing to wait?
Yes -> Samsung ViewFinity S9
5) Is cost the biggest factor?
Yes -> LG UltraFine 5K
6) Apple Studio Display.
