Ok. It is not easy to do a comparison for 'detail' unless you fully zoom in and then that is not fair for a paper map that shows the whole country. Swings and roundabouts.
The GPS map display - you can set the level of detail from low to highest ... and some have a 'declutter' button.
The GPS map designer has a number of choices as to what to display at various levels .. too much and you cannot see due to all that stuff, too little and you don't have enough. This is further complicated by the screen size - you can get more on the larger screen of a home PC compared to a 1" x 2" screen... The designer can chose to have dirt roads show up fairly early or not. Most people are not interested in the dirt roads so most designers chose to hide the dirt roads until you are zoomed in a lot. On the other hand Tracks 4 Australia places the major dirt roads well up in comparison to City Navigator Australia, different 'markets' so they do things differently.
I use both types (vector [what most would call GPS] and raster [what most would call paper]) of maps - though I tend to scan the paper map into a computer and use Oziexplorer to do things GPS with it. I can even convert it to a vector map - but that is a lot of work so it does not happen often.
