If you’re comfortable administering your own system, try Arch.

If you’re not comfortable administering your own system but you want a rolling release, try tumbleweed.

If you don’t want a rolling release, try Fedora.

I’d advise against Ubuntu, Debian, mint, and their derivatives. The only one I know of that doesn’t ship out of date packages is Debian unstable.

If you hate yourself, try Gentoo lol
