It seems that Guix&Nix have many advantages. Could anyone also elaborate some disadvantages of this system in comparison with traditional package managers like debian's or rpm? [Edit] I'm considering a switch to one of Guix or Nix, and I'd like to know if the pros outweigh the cons.

One disadvantage compared to RPM and apt-get is that there are not as many packages available yet.
