If you use nix (especially nix flakes), this consideration falls out naturally from the nixpkgs repository reference (SHA, branch, etc) you choose to track. Nixpkgs has various branches for various appetites for the "cutting edge".
In other words, with nix you decide the spec of the software you want installed on your machine, not the maintainer of your chosen package manager. Depending on your use case and knowledge/experience level, either choice may be preferable.
Also, nixpkgs is definitively the widest-spanning "package manager" on the "market"; see link.
The recent(ish) concept of "nix flakes" means there are 2 related but different mechanisms for achieving this but the end result is the same.
* In the land of NixOS everything is a nix expression including the system packages, configuration files, install image. It's all locked to hashes of upstream sources and is in theory, fully byte-identical reproducible.
