Yes, I manage my Raspberry Pi Plex/Pi-Hole/OpenVPN server using command line because, well, it's Linux.
Also for work I manage Windows Server based systems and although this is a largely GUI based operating system, Command Prompt/Powershell are still tools I use daily to provide more control and depth over what I can do (bulk admin actions, for example).
I don't really use command line out of preference - moreso because it's the necessary tool for the job.
