I swear by paper maps. They are always on, they never crash, there is no subscription. One thing I know, the anything electronic will fail when you need it most. Paper never fails. On the information, detail supplied, ya sure electronoc maps look very cool but do you ever wonder about the accuracy of that data. Like is it possible some of the electronic enhancements are pure marketing spin? Like how many buyers even test, need, rely on that spin.
I use paper only. I fing Map Books gives all the detail I need. Even without elevation contours, If it shows a creek on the left, mountain on the right is it not obvious which way is downhill. If it shows multiple swithchbacks is it not obvious you are gaining or losing wlevation?
I like the challenge of figuring it out, no need to be spoon fed.
ps, on the electronic thing, other than google earth at home planning a trip, I never need it and it is purely a convenience. The actual trip is planned on paper.
