At least in a new car (2009 Pontiac G5), DFCO > Neutral Coasting (for this one experiment).
Instantaneous MPG AFFECTS overall average, but does not INDICATE overall average.

DFCO is still < Neutral coasting, when you consider ALL the inputs necessary to make the comparison.

I leave you to ponder that.
