Which one is better as a performance? Win7pro or win10

Interestingly, while Winderp 10 is ugly as sin it's actually faster than Windows 7. Which is strange considering that never versions tend to be slower than the previous.
But the difference isn't as big as some people put it out to be.

Once you got an SSD the boot times will be roughly the same so it's all down to preference and if your hardware is supported in the older verison.
