https://www.gnu.org/distros/free-distros.en.htmlIf you wish to install one that is more mainstream, some common distributions are Ubuntu and its flavors (Xubuntu, Kubuntu, etc.) for beginners, Debian for intermediate users, and Gentoo for advanced users. Since you said that you have experience with Kali GNU+Linux, you may be able to install Gentoo. But if you do not feel that you are ready, Debian GNU+Linux is still a great choice, although it includes Systemd. If you wish to use Debian but to not wish to use Systemd, a worthwhile alternative is Devuan.
