It's horses for courses, but I concur with both Jochen and Brian, 3d mode gives the user a real view of where you need to go and the layout ahead, names are absolutely no use for normal day to day driving as you mostly likely "know" where you are, (tell me what I don't know, not what I do) if you are being directed then follow the map.

I use mine in 3d wide with full map (even when being directed), like Brian says names are a bonus but really necessary, and for me less is definitely more.

Even with my black Night mode screen, 3d is better.
