Windows server is actually kind of awesome for when you need a Windows machine. Linux is great for servers but Windows server is the real Windows pro. Rock solid and none of the crap.
The worst part of Windows server is knowing that Microsoft can make a good operating system and chooses not to.
This has been the case for ever. I recall opting to use Windows Server 2003 over XP back in the day for desktop/workstation use.
Could even enable XP themes IIRC.
Yes I only recently understood why people use Windows Server as a desktop operating system - it looks and feels like old Windows.
