OpenSUSE. Much like CentOS or Fedora, it is the free and open sourced version of an enterprise Linux distro. In the case of OpenSUSE, it is based off of SUSE enterprise Linux. After playing around with it some, I have even switched to it from Void Linux. I am going to go over the reasons that you might want to use OpenSUSE, including the Software management, Yast, the different release models, installation, and snapshots.
