For the Massachusetts boundary, there are differences on the order of 10m or less for most of the length. It looks like the eastern half is unsourced (or the source was lost in relation cleanups), and the western half came from Tiger. This surprises me, as I'd assumed it came from MassGIS. I trust VCGI more than Tiger, so I'd like to replace this boundary with VCGI data.
I just checked the MassGIS data. It matches neither VCGI nor Tiger, being sometimes closer to one, sometimes the other, sometimes apart when the others are close. Even the horizontal positions of nodes seems to have no relation between the three, except in cases of where a town boundary meets the state boundary.
