I use organic maps most of the time but osmand has much better support for hiking trails: you can see them (not just a path, but the name of the route, with a different color to separate it), I can tell the app to prefer it when building an itinerary, and the altitude info is way more detailed. You can spot the exact altitude and gradient at any spot. You can add a second map as an overlay, and I typically use a contour maps to quickly see where the peaks are, where the route will be flat, etc...

OSMand is slightly too powerful for everyday use, organic maps is the perfect good-enough, less-is-better example.
