'I strongly believe when a system has less moving parts it behaves more stable and responds faster.
The Windows Core is perfect example when there are much less moving parts than in Windows with GUI.
Why is that?
Generally Windows Server installed with EVERYTHING, with all possible features you might not need, especially when you plan to have only SQL Server in that box.

There are three reasons why Windows Server with Core is better than Server with a GUI:
1. Security: Core has less features. That means less surface for intruders to attack.
2. Management: No unnecessary updates and planned reboots.
3. Resource consumption: Less memory usage and less CPU overhead'...
