I don't know if anything is winning. I do have my preferences and others have theirs. I can tell you that reading on a tablet and reading on a phone are distinct experiences, even for text-only material.

Looking around, the younger generation doesn't do any reading on their phone. I see a lot of scrolling so probably social media or tiktok. The older generation doesn't do any reading on their phone as I see them carrying paperbacks. That's for the people who are still reading books(physical or digital) which seems to be diminishing every passing year.

Photography, is a different area. The more capable cameras on today's phones have sort of killed the mid-range market of cameras. As an amateur photographer, I haven't used my mid-range DSLR in a long time now and keep it for when quality of the image matters.
