Honestly hard to say. Very much have respect for existing ubiquitous tools and for their copyleft and open source advocacy but they come across as very 'elitist' and reluctant to move to more common open source patterns (for better or worse). Like it seems that contributing to a GNU project seems challenging in needing to get involved with mailing lists and emailing patches etc. Although it seems GUIX uses Codeberg so maybe that stance has softened a bit.
