Every time I use Linux, going back to Windows is always a pleasant feeling. I particularly find Windows 10 the most modern and connected to cloud services among the desktop OSes. (Yes, you give up privacy for convenience, but I'll happily take that compromise) More importantly, the software I need for work and pleasure is simply not available on Linux. Apart from that, frankly there's little to choose between a modern Linux distro, Windows 10 and macOS Sierra. They are all solid operating systems.

Of course, you're spot on - for mission critical applications and developers, Linux is the way to go. But I'm just someone who uses their computer to get work done and for entertainment. Windows 10 is the best choice for me and many an average Joe.
