Drive is pretty decent
Nokia Drive is accurate and decent, but, the lack of lane assist and the constant recalculation and inaccuracy of the ETA are frustrating.
Maps is great for directions or if you're navigating for another driver, but, it's lacking for voice guided navigation while driving.
Garmin Street Pilot is very excellent, though expensive, despite not being able to preload an entire state map. It'll still have your route, at least, if you lose your data connection.
