I like having a GPS I can just leave in the truck. My cell phone stays in my pocket or in the cup holder.
For my tow vehicle that's a Garmin 760 I bought at deep discount on a black friday sale (it was discontinued, replaced by the 770). The voice recognition on the 760 works SO MUCH better than Google, and doesn't need a cell connection to work.
For my daily driver, that occasionally goes on long trips, it's a 12 year old Garmin Nuvi.
Both have lifetime maps and traffic. The few times I've run into traffic neither the Garmin nor the all mighty "WAZE" could do anything about it, as there was no way to access an exit, or the side roads were just as clogged as the highway.
I don't vacation in cities or urban areas, so crowd sources traffic is of little use. While traveling to a destination, an accident or traffic jam in the middle of nowhere, there's not many options. I'm glad I have a kitchen and bathroom hitched up behind me.
