I haven't seen this talked about yet, if it has then my apologies. Just gave a quick read to this lengthy comparison posted at:

I haven't read all 3 articles yet, but there's a ton to digest here.

Most importantly, it vindicates how a lot of people feel about film, especially with respect to detail. Almost as important, it lets the Luminous Landscape folk eat a little crow on their prior 6x7/4x5/8x10 v Phase One comparisons.
It also vindicates my frustration over a lack of decent enlarging options (low quality of consumer scanners vs lack of darkroom access for optical enlargement.) I guess some things don't change!
Yes, that is indeed one of the best comparison tests made.
Very good work.
In the past the internet and the photomagazines were flooded with these nonsense tests "scanned at 4000 ppi with amateur scanner" vs. digital sensors.
And then they said it was a "film vs. digital" test. BS. It was not.
It was a digital (scanner) vs. digital test.
And 4000 ppi scanners can not exploit the full potential of film, not at all. The quality loss with 4000 ppi scanners is huge.
Zeiss did several real film tests and published them in their camera lens news. Their results:
Spur Orthopan UR: 400 linepairs per millimeter (lp/mm)
Agfaortho 25: 250 lp/mm
Agfa APX 25: 200 lp/mm
Kodak TMX: 180 lp/mm
Fuji Acros 100: 160 Lp/mm
Fuji Velvia: 170 lp/mm
With a 24 MP FF sensor the maximal resolution is 85 lp/mm. That is the Nyquist frequency, the absolut physical limit which cannot be surpassed.
In reality most 24 MP sensors have a real resolution of 65 - 75 lp/mm because of the AA filter which is reducing resolution.
Some photographers and me have tested the D3x in comparisons to different films:
We've got 70 - 75 lp/mm with the D3x.
We've got 120 - 140 lp/mm with ISO 100 slide films.
We've reached 115 - 150 lp/mm with ISO 100 T-grain BW films.
And we've got 160 - 250 lp/mm with high resolution BW films.
Our test results have been a bit lower compared to Zeiss because we've used a lower object contrast.
There have been other tests published by Antora; Seemann, Serger; Ventzke with similar or even better results for film.
And all these tests included scanning, optical printing and slide projection:
With optical printing and slide projection significantly better detail rendition is achieved compared to 8000 ppi drum scans and especially 4000 ppi amateur scanners.
Drum scanners are limited at 110 lp/mm with medium object contrast, 4000 ppi at 70 lp/mm.
But one important area lacks in Tim Parkins test: slide projection.
With slide projection the best quality at huge enlargemt sizes is achieved. Best resolution, best sharpness, best brillance.
Digital projection can't compete at all with slide projection, because of the extremely low resolution of the beamers (only 2 MP in horizontal direction, even 40% less in vertical direction) and the bad color rendition.
In digital projection you have the situation that you pay 7000€ for a 24 MP D3x, and then you have to pay another 7000€ for a beamer to get the 24 MP of the camera smashed down to 2 MP of the beamer.
What a ridicolous waste of money.
We've did the direct comparison of 35mm slide projection and the most expensive 2 MP 7000€ beamers.
The slide is a league of it's own, no chance at all for the beamer.
