As a standard productivity desktop? Linux

As a gaming platform? Windows

As an infrastructure (DHCP, DNS, router, firewall, proxy, etc), print, database, file, or web server? Linux or FreeBSD though in certain circumstances Windows must be used (web application requires the Windows platform or it uses T-SQL and must be hosted on MS-SQL).

As an applicaion server? It depends on the applications it is hosting - either Linux or Windows.

My favorite is mac 💻, safe and durable. Fullfill all my need.
