Best way do describe the differences between Linux and Windows to average person?

I've been having a little trouble with this. It's only happened once or twice, since I don't usually ever mention Linux but there are times when it comes up and I'm not great at explaining the differences and why I personally believe Linux is far superior.

Average computer users don't have any idea about scripting and the advantages that writing scripts can provide you in automation. What are the most important differences between Linux and Windows? (I'm leaving OSX out since it has the Zsh and in a way it is Unix-like (please correct me if I'm wrong))

Thanks!
