Complete dependence on electronics for navigation is not a good idea but we live in a world where some folks cannot tell the time from a clock that does not have a digital display or read handwriting.
I'm a surveyor, so I love my paper topo maps. I think its easier to see a larger area when using the maps to pre scout. My favorite so far are the National Geographic maps that Sportsman's Warehouse sells.
I had too many bad experiences with GPSs and now more recently phones to rely on them anywhere serious. Electronic maps and the info rich apps like onX are exceptional and bring a lot of value that maps can’t. However your phone or your GPS can go down at the wrong time for a lot of reasons. Paper is the best back up when it really counts.
I use paper maps when I'm not in checker board for several reasons:
In the back country I don't need extra charging packs or electronics, just a light weight map and compass that won't die. Plus, if I start ranging I don't have to worry about whether or not I downloaded the area ahead of time. Secondly, looking at a big picture gives you a lot more SA on the area than just a small screenshot. Thirdly, when your hunting buddy asks for tips for his next hunt you can pull out your maps that look like an art project with scouting notes for unprecedented street cred.
