Maybe not a duplicate, but very similar to:

Advantages of Gentoo vs Arch Templates

What would be the advantage of using a Gentoo or Arch Template vs a typical Fedora template? I assume it’s largely personal preference and possible different default package managers, but they both use systemd correct? Is there any security / hardening advantage to using Gentoo or Arch in the context of a Qubes template? I have a Fedora templates, and if there’s any advantage to switching, I’d make the move.
