a landscape camera vs a sports camera vs a portrait camera?

It isn't a general rule that more resolution equals more noise, the R5 is very good. Canon is getting much better in this regard each generation.

Most of the time yes. However, when downsampling to a lower resolution it will usually look better then a camera that nativity shoots at that resolution. For example, I used to own a 5DS alongside my 6D. 6400 on both at their native resolution, the 5DS looked noisier. However if I downsampled the 5DS to the same size as the 6D, the 5DS appeared less noisy than the 6D did. It wasn't a huge difference, but it was noticeable.

I agree, but this is why I like the larger resolutions. I can do a very mild NR, then resample down, and then post process further, and I can make that gap even larger.

I have fan posters printed from the 5D4 at ISO 32000 for example.

Are portraiture shooters benefiting from the 50MP of the 5DS?

That would really depend on the kind of portraits that they are taking.

For someone looking to take simple headshots, like the guy who the High School hires to come in to take yearbook photos, I can't see any useful benefit.

But for the fine art portrait photographer who creates portraits that are masterpieces, such as Brooke Shaden or Lisa Holloway, I can see instances in which 50MP files would yield a tangible benefit, especially for images that are printed at 3 or 4 feet across. . I can also see a lot of benefit for those who specialize in fine art environmental portraiture.

I agree. Seeing inside the pores in a headshot is not attractive detail!
Having lots of pixels for greater detail in an environmental portrait could be beneficial.
