I grew up as back seat navigator, with paper maps and almanacs. Lot of family road travel. So paper is still my primary. But I am much enjoying trying several offline digital topo off-road map apps on a dash-mounted 7" android tablet. Great for zooming in and out of an area and marking or flagging things of interest in the area. I'm very much liking the map importations with Backcountry navigator. It's very similar to the old Garmin importer. And I have my Garmin handheld along too. One is None, Two is One, Three is for me. Water and maps and communications, redundancy is good.
