(Used 15ys OSX, now Win11)

The biggest difference between OSX and Windows is, Apple adds (some say steal) functionality from competition, and open source. They make it neat. On windows to have something working, you need a WezTerm, Everything for search, Windhawk for a vertical taskbar on the right, Powertoys for an app starter, Folder Size for disc management etc. If you spend a lot of time, Win11 can be ok to work with.

If Powerpoint and Affinity would work on Linux, I'd use Linux though.
