For personal use I reckon Win10 smashes it.
Use it on Surface Pro3, HP Laptop and Desktop, no issues once it went mainstream (there were a few glitches when it was Insider Ring).

I love it.

For business, I would be waiting until others have used it to see what pops up..
Very hard for most businesses to move away from Windows, but just wait a few more months. imho
