Linux Mint with Cinnamon (or XFCE before that) was my daily driver for a while, really nice distro that just works and gets out of your way for the most part.

I do personally find the UI of LibreOffice to be good enough (you can even change it into a ribbon layout if you’re more used to how MS software works), the only complaint I have is that for whatever reason it works really slow on my current Windows install. Oh well.
