It depends on your definition of "best". I agree with you from a technical point of view but this is not my sole decision criterion. I had setup an Active Directory server on a Raspberry Pi for serving my Windows 7 clients. I would have loved to continue using Windows as I think it is great technology. However I was switching because of some crucial decisions by Microsoft: 1. Shoving unwanted "features" along with security updates. As much as I understand Microsoft in wanting a more uniform landscape this is a no-go for me. The only reason I was not hit by the Windows 10 mandatory upgrade was the fact I had the machines in an AD domain (or at least I suspect so). 2. Phoning home without any recourse for me to even know what is collected. How long it is stored. Remember: innocent data today could bring me in trouble tomorrow. Collection can change any time without me even noticing.
