Have a look at https://www.funtoo.org/Funtoo_Profiles. Funtoo had a very different way to configure your version of the distribution, especially if you are used to something like Ubuntu. It was a spin on Gentoo, I think later diverging a bit more. And it opted against shipping systemd (ever) and wayland (until tested, say the docs), which is a minus for some and a plus for others, but certainly rare.
