Best GPS?

I use a cell phone app called waze. It is a gps but it also is crowd sourced for traffic. The more users in an area the better it is at detecting traffic issues. The few times I thought I was smarter than it I was stuck in traffic. It works great around populated areas but out in the country where there are fewer people updating it, it may not be so good at traffic. At one time it would only route if the destination was under a thousand miles don't know if that has changed or not. I still use it for my local area even if I know a route just in case traffic backs up.

I also still keep an atlas in the vehicle as well. I like maps.
