1) Nix language is ugly but it's pure. Scheme is not. To my taste it's even harder to reason about/debug/introspect because of lack of purity.
2) Guix itself lacks any nonfree software/blobs, which is essential to run a real desktop. That is a showstopper for newcomers and in my opinion that's what prevent the community growth, so there are much less packages, docs, etc.
2.1) There were channels to add nonfree blobs, but channels make system less reproducible and they were unofficial. Maybe I'm not up to date with the Guix developments, but as far as I'm aware there is no replacement for Flakes and a system with multiple channels is not reproducible and easy to break.
