Best of the lot

First let me note that I own the Navigon, Tomtom, coPilot and motionX GPS apps (yes, Ive spent a fortune) and I consider Garmin to be the best GPS app Ive found considering both usability and accuracy. It operates nearly the same as the Garmin GPS I have in my car and with the traffic add on usually gives me the best routing option. Is it perfect, no, but none of the others I have found are any better and some, in particular the free options such as Google maps, are much worse when it comes to accurate directions. YMMV.
