In my humble opinion, there is a lot of difference in complexity depending on what you're trying to do. If you just want to build software, then, like you I agree that is quite easy. If you want reproducible builds, things start to get tricky. If you want deterministic reproducible builds, then it get really complex. Guix goes beyond being a simple package manager/build system. It has a ton of features, even more if you read about GuixSD which is a complete distro managed by Guix. Really wonderful stuff inside.
