There’s Two Main Choices:

Packages…

1. Pacman-based - Arch, Arco, Endeavour
2. RPM-based - Fedora, SuSE
3. Aptitude-based - Ubuntu, Debian

Choose Pacman for rolling release, bleeding edge. Pick aptitude for servers and pick RPM if you want something that ‘just works’.

Desktop…

1. Full DE - Gnome, KDE
2. Window Manager - Awesome, i3

High end machines with lots of fancy features and ease of use pick a full DE. WM is good for speed and low-end hardware but harder to use.

I don’t understand the obsession with rust.

Someone mentioned Linux!

I use Arch btw.
