I quit using paper maps several years ago. I'm 73 so it is not because I'm sticking to my old ways.
It seems every time I tried to use a paper map the area I was interested in was on a fold seam. I also didn't like having to unfold a map to some incredibility large size! I'm usually on my own so I don't have a navigator. Something like an atlas also gave me issues because I was always changing to another page.
I go to the UK a lot and I used to drive until I got lost, pull over and look at the map. Now I just program my destination in and let the software do the work. In 2016 I picked up my new BMW in Munich using their European Delivery program. I would just input my destination into the cars nav system and it would take me there, every time!
I use Google Maps and Here. I use Here because I can download maps for a state or country where Google Mapsneeds a network unless you go to the trouble to manually download a section.
I do a lot of hiking and I use My Garmin GPS wit topos or another app I like is Gaia Maps.
