I have used many desktop operating systems and I keep coming back to Windows. I tried OS/2 back in the day, and found out that, while it was very stable, it lacked the applications I could find only in the MS-DOS/Windows ecosystem.
I tried Linux a few times. I tried many different distributions over many years. Ubuntu, Mint, Debian, OpenSUSE, Fedora, Red Hat, PCLinuxOS, just to name a few. All of them lacked polish. And they lack the apps. Of course, there is also an open-source counterpart to Windows commercial apps. But then I find out they lack polish and that some of them are very basic. I tried to wait for some of them to be developed and unleash their potential, but, 10 or 15 years later, their pace of evolution is still just lacking. Linux is an absolute no-go for me. It was by using Linux that I started to value commercial software more.
I first used OS X in 2008, and I finally found Windows' match. Since then, I have been divided between Windows and macOS. Both were very polished. Windows had more software available to it, but macOS run on more premium hardware. More recently, though, I have to say that I chose Windows as my main operating system. Yes, macOS is fine and it runs beautifully. But Windows is great and it has evolved well. It runs the software I need. Games are usually developed for Windows. Microsoft Office, which is the software I mostly rely on, runs way better on Windows than on macOS. And, thanks to Apple's lead, Windows machines have evolved a lot in the last 10 years. Windows machines are generally cheaper and there are plenty of choices to choose from, and many of them are good now, some as premium as a Mac. In the end, both are good, but I chose Windows as a matter of convenience and practicality.
