What is better windows 8.1 or 10?

Answer 1

Windows 10,It's growing on me.

Answer 2

Windows 10. I never like having that three-page desktop with the app page, app desktop page, and the traditional desktop. I got used to working with it, but I much prefer Windows 10, and I was late upgrading for free. I've grown to like Windows 10, even better than Windows 7, which was on my other PC. 

Answer 3

Pretty much every OS is better than \Windows 8.1
