I have City Navigator NT and it is definitely more accurate in the vast
majority of areas. However you mentioned one free alternative, so I
mentioned another.
Note that Ibycus is based on "census data" which I guess means TIGER
data. That data set (for Tucson at least) is IMO quite poor - the roads
are not aligned with reality, glitches, missing roads, etc.
OpenStreetMap uses TIGER data as a starting point but at least everyone
can work to fix it, which will result in better accuracy. Already quite
a few sections of Tucson have been fixed.
