Here any in-car navigation - even in my wife's 1 year old Seat Leon - is never as up-to-date as either of the major native Maps apps (Google or Apple). I exclusively use Apple Maps for navigating in the Netherlands (and elsewhere in Europe). I can count on one hand the number of times it's led us astray.
In fact, I think more like two fingers. The one time that stands out is navigating through back country in Croatia this summer. Both Apple Maps and Google Maps seemed to think a road existed that simply wasn't there, causing a massive detour to get home.
Otherwise, my experience of Apple Maps is completely the opposite to yours. Where have you been using it?
Edit: Also, OpenStreetMap is the best Maps data for anything off major roads here in Europe - it beats Apple and Google by a country mile. If you're going hiking or mountain climbing, OSM is much better.
