For opening a very large and organizationally complex PDF like the ARMv8 Architecture Reference Manual, Preview.app is the only PDF reader, on any platform, which I would recommend. The competition is simply a joke in comparison. I also like it for filling out PDF forms; I think I ended up using a web service (!!) the last time I wanted to do that on another platform. But aside from Preview.app, I don't find anything commendable about macOS. I've remained on an old and vulnerable version to ensure I don't lose control of my own hardware, and what's more, I will never upgrade that hardware given how bad the new hardware seems. In short, I'm just waiting for a Preview.app clone/same-weight-class competitor on Windows and I'll be off to one of Msft's first party laptops.
