[time-nuts] GPS question

Am I correct in assuming that the position given by a WAAS enabled handheld
GPS unit is more accurate than the position reported by my Z3801?
Specifically, I tried a Garmin eTrex Legend Cx with WAAS enabled and used
averaging mode for the waypoint.
On a related question, the eTrex reported that the position was +- 6ft. Is
that really 6ft, or is that 6ft in addition to the 3M claimed accuracy of
WAAS?
Thanks.
