maps.me is ok if you want a-b navigation, but rubbish in terms of anything else including accurate location or to develop you own routes.
Yes people have used it to drive across Africa etc but they only follow the route it gives and rarely deviate from that route.
OSMand is better but just remember they charge you for maps they get for free from OSM.
Gaia GPs and Locus Maps are about the best proper navigation tools via apps but still not as good a dedicated GPS unit with good mapping. Last time I looked ONX was limited to North America mapping
A quick look at HERE's maps for a remote part of the Sahara I know well shows, inaccurate plotting of roads and incorrect Road numbers
