I'm literally deciding which distro to install as a first timer. It's my understanding that Mint is the best for beginners migrating from M$ but knowing nothing about why this is the case one thing nags me:

Why do people switch distro's? What isn't in Mint that you get elsewhere? I really don't want to waste time using Mint if I'm just going to have to reinstall something else because it turns out it is bad for gaming or doesn't support many devices or something.
