Is it bad practice to do everything through GUI utilities? I run web servers hosting multiple sites, and a VPS, along with a bunch of crap for my home media center like plex and utorrent.

I use windows for my server and most of my VMs bar one, and always opt for gui configuration. I never SSH into my server, I just use remote desktop. I know I could save a LOT of resources without the gui using linux, which I am quite familiar with. I'm just not sure whether it's worth the hassle of re learning everything to move to a command line linux enviorement for all my VMs. I am considering the move, and have NAS space to migrate the files, is it worth the hassle for the extra resources?
