Arch Linux
Didn't tried it yet, but
Probably not, because it is a binary-based distribution, doesn't have binary bootstrapping like Guix System does and packages are built in whatever environment with whatever compiler, not to mention systemd, which is a fucking Swiss cheese of security, because it is bloated and it's devs don't care about bugs.
Or Guix System. It is based on Nix but has some extra features like for example system-wide configuration in one language - GNU Guile.
gnu.org
In the sense of it being inspired and not in the sense that the Nix package manager is a base of the project.
Nix seems to do this for the most part. Sometimes you do have to do a DSL in strings, but for some packages you can do the whole thing in pure Nix and is a goal for the project. It's just that converting every programs config stuff into nix is a lot of work.
I second GuixSD over Nix. It just feels a lot better OOTB.
Well, actually they hard forked nix package manager. But hey, isn't that how free software works?
gnu.org
Well what which OS would you suggest for a daily driver? Often have to use many packages. Don't have much specs on my laptop, to compile a lot of those programs.
Yes, only because it actually supports bleeding edge software development
No
Nothing is secure
Windows ME
its like win2000 but with dos instead of nt
