I think that "drawing all of the nodes and points manually" is an
important difference, from a quality point of view. Each node or way
that you draw by hand, is carefully considered and placed, one at a
time. It isn't perfect; nothing is. I suggest that this leads to a
kind of automatic quality control, as the nodes and ways are placed.
To give an example, look at this imported building
http://www.remote.org/frederik/tmp/funnybuilding.png
Note how the main building consists of 8 separate parts plus a strange
diagonal line, and note how the smallest parts are just about 2 metres wide.
Compare to the aerial image:

A very careful tracer of the aerial image might indeed have created more
than just one shape for this, but there is hardly anything there on the
imagery that suggests *such* a complex edifice.
This is not an example that you only find after a long search; it is a
typical cadastre import building.
Bye
Frederik
