For a home user, it's only good for the supplier, since the average home
electricity meter does not measure power factor.  The home owner probably
doesn't care either way, he gets no financial gain for presenting a good PF.

For an industrial user then both.  The supplier's tarrif depends on the PF
of the users equipment, so it's in the interetes of the user to get as good
PF as possible, and in the suppliers interest to reduce the peak currents in
his transmission lines.
