Disclaimer: I work in IT, so I'm familiar with getting my hand dirty with computers.
I'm using Ubuntu because I know it and I want stability (in the past I experimented a lot with other distros). In fact Ubuntu is the main OS in all of my computers, and my wife and children are using it without not too much issues. I keep a partition with Windows 10, but only for some games that doesn't get well emulated with Steam Proton.
So far, not much problem for the usage we do.
Yes, the git part is amazing, as well. Not only you can keep track of changes; you can also see your daily progress and word counting :) Totally recommended for any text based workflow.
