Nick, I have experienced that GFI breakers tend to have a much lower
incidence of nuisance trips than GFI receptacle.  The price however tends to
be much higher, and since most new homes require 2-4 GFI circuits depending
on configuration the cost will add up, so being the ever wise masters of all
things with wire the electricians don't seem to use them.
