This is a most excellent place for technology news and articles.
That doesn't really matter too much and is mostly personal preference.
The biggest difference is which package manager and how up to date each program in there is. Arch and OpenSuse Tumbleweed will have quite up to date packages as they're rolling release models while Mint and Ubuntu tend to be a bit slower and more stable.
I suggest going through the installation process of Arch linux at least once because it does teach you the basics of Linux but for usability you'd be better off with a distro that has a GUI installer.
