Last summer I set-up a tripod at the end of Chicago's Navy Pier to capture the Parade of Boats for the annual Race to Mackinac Island. I shoot 6 rolls of film over a 3-hour period. In a few of the background / environmental shots, I found that I shot several scenes of Chicago over and over. Here's three versions of roughly the same South Loop Skyline. For those familiar with downtown Chicago, the boats in the foreground are in Monroe Harbor and the center buildings are clustered around the intersection of S Michigan Avenue and Roosevelt Road, just across from the south end of Grant Park.
The images are not back to back, nor shot with exactly the same settings. They just happen to have almost the same view, same lens, same camera, and same focal length. A difference in sunlight probably contributes most to the visual differences, more than the difference between the B&W vs color, and the differences of the ISO speeds of each film.
This first image was captured second overall. I know this because the EOS 1v labels the physical film with an ongoing sequential number of rolls used. The B&W uses Ilford Delta 400, at an effective ISO-200. All the scanned JPEGs have been processed in LR6, so these aren't straight from the camera or scanner.
I prefer this B&W version to the last B&W presented in this sequence, especially the details and contrast of this image vs the later B&W, even though the later version is shot with an orange filter with the goal of increasing contrast. The sunlight onto the building probably really impacted the results.

This second image was captured using expired Fuji NPS 160. I really like this film, where my stockpile is nearing the end. This roll was labeled with an expiration date August 2001. I'm not the original owner, where I have my rolls frozen except for those I plan to use in the next 6-months or so. None of my NPS160 rolls have had any problems, so the rolls were likely kept frozen before being resold to me.
There's a bit of a film grain, but nothing like the Delta 400, where the Ilford Delta is known for having a fine-grain for a 400-speed film. The grain for film speed is not linear. My finding is film grain is more a function of the film type and shooting conditions / exposure, rather than simply the ISO-speed of the film.
This image is nice. It just doesn't have the nicer light of the first image.

2022 Boat Parade - Race to Mackinac The third image returns to Ilford Delta 400, this time with an Orange filter. The effective ISO was adjusted to ISO-080 to account for the 2-stop impact of the filter, and then a bit more exposure for this film over the box-speed. The image contrast shows my preferred result of using specifically an Orange filter with Delta 400. The light just doesn't seem as nice as the timing of the first image.
The grain seems roughly the same as the earlier B&W, maybe even a bit less pronounced.
This image was the first of the day in this 3-image sequence. There were storms passing north and south of the city, with rather overcast skys in the early portion of the morning, changing to bright sunlight in the afternoon. That subdued light likely impacted this image.

2022 Boat Parade - Race to MackinacI've given you everything I see, know, remember about that morning nearly a year ago. Do you see any other aspects I missed in the comparison? Is the color vs B&W important to your shooting, choice of film, if still shooting film?
Wait, here's a fourth bonus image I found in the 2021 results. My position at Navy Pier was slightly different by about 10-yards between 2021 and 2022, but still with the same camera and lens, this time with Kodak Tri-X 400 and a Yellow filter. The time of day was similar, but a more overall sunny morning. The 400-speed film again was adjusted for the use of a color filter, this time ISO-160. When I look at the details of image 3 and 4, the Ilford Delta seem to have less pronounced grain and more fine detail.
