I cant say for 100% sure weather or not its better but here is what I can tell you.
Typically on the GPS screen it reports that my accuracy is 8ft with waas and around 10-11 feet without. I have recorded several geocaching trips as well as walks I normally take. The tracks have matched up with Google Earth very well. I have not been a victim yet of the drift problems I have read about.
Again I am no professional just telling you my experiences with the unit.
Edit: O and by the way I am currently running the 2.41 beta software for the gps im not sure if that fixed any of the tracking problems or not but iv been using without problems and really enjoy the added features.
