The better one.  If the math is sound the presumably the better position
results in better time.
If there are correlated defects then I suppose the GPS provided solution
may be better.

None of the various surveys for my primary antenna (which is not optimally
located) agree and all are "wrong" compared to carrier phase solutions.
The delta between the various units (Trimble, uBlox and whatever is in the
Fury) is greater than the delta between my indoor and outdoor antenna
positions in xy.  Z not so much.
