It has most of the annoying things that plague consumer versions of Windows 10 stripped out, and it gets a very different cadence of updates, restricted to security and quality fixes. No Cortana, no Edge installed by default, no built-in Store universal apps.
It's rock solid; I have never gotten a bad update pushed to any of my boxes running LTSC over the past five years. If you want a Windows workstation that just works, and will continue to work without fiddling, this is it.
