From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Nix is better because you can use a lock file to fetch the exact revisions of each software. Even proprietary stuff is hashed so when you download it, it's checked to be bit identical to the lock file hash before it's installed
This means your setup on another machine is the same as long as the lock file is the same.
Also you can switch to an older revision, mix and match stable and unstable, keep your whole setup in a git repo. It's basically everything you ever would want from a package manager (reproducible builds already done for the minimal version, soon coming to all 80,000 packages)
