I prefer Windows 8 but people people complain a lot about it. So, check out the reviews and go for the one you like out of them. Anyways if you are talking about performance the Windows 8 is better on that front. The benchmarks from the LinusTechTips channel show that the Windows 8 is just a little better in performance.
I prefer and like the Windows 8 with the unofficial start menu app, but opinions might vary between other people. Most people do not like the Windows 8, but I personally do.
