Windows: Sumatra PDF.
Linux: Zathura.
These are so much better than Acrobat. Might not do everything you can imagine but they are excellent and a very good default.

Apple has been quietly using the same screenshot functionality since the 90s, and has continually iterated over improvements on Preview since the early 2000s.
I find the macos shortcuts to be poorly chosen and un-discoverable, but they've stuck with it, so finding how to take a screenshot is extremely easy.
Microsoft:
Microsoft is on their third major revamp of screenshots. There are six(!) different ways to invoke a screenshot on Window 11 - printscrn key, Win+Shift+S, snip and sketch, snipping tool, game bar, pressing the volume up+power buttons on supported devices (but not all). Microsoft's official website suggests third party tools in their app store as well. Each way offers different options (such as whole screen, individual app, cropping, etc). Some options quietly redirect you to other options, while still offering the previous option in contextual menus. Options will vary in where they place the image as well - filesystem, clipboard, or directly into a window for you to chose.
Microsoft uses their browser as a featureless PDF reader. Other Preview.app functionality can be found within a combination of paint.exe and the new Windows Photos app - each with a completely different UI paradigm. They do not have an OCR solution - or if they do, I haven't found it.
My understanding is that Windows 12 is a direct attempt to resolve a lot of these issues, and that Windows 11 has been deemed "transitional", but it's still extremely exhausting. I personally still prefer Windows over macOS (for a lot of reasons unrelated to Windows' incredibly boneheaded rough edges); but, please, Microsoft, what the fuck are you doing!?
