Let us first get the basics right.
Windows 10 is actually an improved/updated/modified version of Windows 8.x. And Windows 8.x is nothing but an improved/updated/modified version of Windows 7. So, by definition Windows 10 has the most mature code & technologies as of today.
Well this is what i believe also. There is always a "BUT" remains.
My favorite version of Windows is still Windows 7.
I also do not hate Windows 10, but forced updates (even over metered connections), horribly created icons, slower boot times, start menu and no actual start screen besides the piss poor one they added that deserves to get set on fire, no charms, Cortana being a ****, forced driver downloads.
