Using the Pixel 2 XL, I find that it is more than adequate for my walkabout shots. But I still pull out my DSLR for my wide angle shots or BIF.
I haven't taken the time to see how the Pixel files hold up to PP, especially for low light.
I'm fortunate to be old. Sure, the Pixel camera can't do what a 600mm lens can do but then neither could my first camera, a 2.25 twin lens relfex.
If I were into birds I wouldn't use my camera but I'm looking forward to the focus feature that locks on a subject--dog, child, otter, whatever--and holds the focus and the subject moves. That would be great for my nephews soccer games.
For wide-angle I use panorama. I'm using the new zoom feature on my Pixel 2 while I wait for my Pixel 3 with hi-rez zoom but even on the Pixel 2 it isn't bad.
I do minimal processing but I like being able to shoot RAW is I choose.
Old photographers are used to adapting shooting to the limitations of equipment.
