Similar situation here. Google Maps had finally gotten decent to the point it was usuable up here in Rural NH. Now with Apple Maps, the road data is cruder, a much larger fraction of "not really roads" are incorrectly shown as actual roads, and the address lookups seem to be quite incorrect.

Part of this is the shift to TomTom as a data source (at least here).

The interesting thing? TomTom North America's mapping database operations center is here. Two of my friends that work there mention that they can't actually use their own products to route from their office to their house...
