Opensource :

Linux is fully Open source & it’s complete source code is available everyone.

Conclusion :

Linux is much more cutsomizable. It can be anything you want it to be, from a desktop to a server, laptop to a tablet, my house to US Army rifles. It’s meant to be everything, and it’s damn good at it.
