This is the best aerial view shot I have seen of the One Nation Rally. It is clear that Beck's Restoring Honor Rally was much, much larger (maybe 10 times larger if not more). There is one caveat; it is possible that this picture was not taken at the peak of attendance. This image does show more people at the rally then any other I have seen so I will assume this was the maximum until a picture with more people surfaces.

Compare that photo to this one of Beck's Restoring Honor Rally.
