‘guix install’ installs into the current user’s profile which can be
found at ~/.guix-profile whereas ‘guix home’ creates an immutable
profile under ~/.guix-home/profile.¹  You can install the same package to
different profiles but of course they will be built only once (provided
you use the same Guix revision).  You can list the packages which are
installed in your Guix home profile via:

  guix package --profile="$HOME/.guix-home/profile" --list-installed

Best



¹ IIUC the profile under ~/.guix-profile is also immutable (as are all
  profiles).  ‘guix install icecat’, for example, would create a new
  profile that contains all packages from the previous generation of
  ~/.guix-profile plus the packages icecat and then it would link the
  new profile to ~/.guix-profile.  In contrast you cannot do the same
  with ‘guix install’ for ~/.guix-home/profile.  Invoking

    guix install --profile="$HOME/.guix-home/profile" icecat

  to try to install icecat to the profile ~/.guix-home/profile yields:

    guix install: error: open-file: Read-only file system: "/home/daniel/.guix-home/profile.lock"
