Great comparison! At 4:30 or so, there are subtle differences in the cloud graduation with the images on the right (Aristadol?) having a slightly more dramatic transition from midtones to pure white highlights vs a more gentle gradient from mids to highlights in the sky. Most anywhere else, especially in the shadows, the differences were less obvious.
12/10/21 That was pretty cool where you took the prints and scan them and used the computer to see the differences between the two prints which was hard to see by eye alone, a great way of combining film and digital to get results or comparison. No other need for densitometers or other equipment.
Interesting video, would be great to see a comparison against a hydroquinone free developer verses Dektol. Something like Tetenal Eukobrom AC. I do like powder developers and fixers as they reduce on plastic waste while keeping cost down and you are unless to ran out so easily.
