Remember if you plan us use Linux, it is pretty good at what it does. Not perfect sometimes, but better than average. And it is limited in what it can do. For general desktop stuff, it is adequate.
But you can't beat free and the fact that it supports old hardware (computers).
I love Ubuntu because of the level of support of almost all hardware and packages and love the Mint desktop. You can install Cinnamon on Ubuntu and make the desktop act like Mint. That is my preference. The best of both worlds. Ubuntu depth and Mint friendliness.
For non-Linux people there is a prepackaged version @ https://ubuntucinnamon.org/
