Going to be honest here
Windows is good for general professional use. Linux is absolutely terrible. MacOS is also decent.
Professionals use windows because everyone knows how it functions, it has robust and supported user management and Microsoft provides significant enterprise support to companies using their operating system.
Linux only has some of those features, they’re often half-assed or unsupported, and there’s no central authority for help.
It’s fine for personal machines, but I absolutely disagree that the only thing windows has going for it is popularity.
I’ll go Linux when I don’t need any more windows based software, and there’s been almost 0 progress made in that sector in the last 5 years.
Between games that don’t run on Linux (Apex, CoD, any other shooter) and professional tools such as Lightroom and photoshop, there’s no way to switch to Linux without needing to boot back to windows multiple times per day.
