"Windows 10 and Server 2016 look very much alike in terms of interface. Under the hood, the real difference between the two is simply that Windows 10 provides Universal Windows Platform (UWP) or “Windows Store” applications, whereas Server 2016 – so far – does not. Therefore, if you have any requirement for the provision or usage of UWP applications, then RDSH is not yet a viable option.
But that aside, there is no real difference from a user interaction or experience perspective. The decision needs to be driven by other factors... "
IMO W10 as a clean install runs really fast. Even on my dad's old laptop with a slow SSD, 2GB system memory etc it starts and runs very quickly.
Things slowed down a lot due to the added APPLICATIONS, though frankly that's mainly just from a cold boot. W10 is very responsive once things load up (a minute or so).
I doubt SERVER 2016 would benefit the average desktop user.
