I don't have the comparison data back from the survey crew yet but my initial impressions of the Aeropoints are positive. One of my 10 points didn't upload for processing but the rest were uploaded to Australia, processed, and returned as a csv file within about 2 hours. The limitation on the speed of processing appears to be the frequency at which the local base station makes data available.
I didn't end up using Ground Station Pro for the flight. I had some problems and a few messages about the firmware then decided to just use Drone Deploy so I could get my test of the Aeropoints finished. I will dig into it soon though.
