Pro Obtains data from community-based OpenStreetMap
MAPS.ME uses data from OpenStreetMap, meaning the data retrieved from that service is a community-based map. Anyone can freely edit and contribute to the map, a map concept that is similar to Wikipedia.
Pro Includes offline routing and turn-by-turn navigation
Users without a data connection can still use the app for turn by turn directions, which is great for those that travel or use a device that does not have a cellular data connection.
Pro Fast rendering
By using compression of the map data, MAPS.ME is able to speed up the rendering of their maps to ones device. This allows for a quicker feeling app.
Pro Matching modern material-like interface
The design of the app uses a material-like interface making for a close to native looking experience on Android.
Con Being based on OpenStreetMap data can be lacking
The use of OSM also has the drawback of many places not getting the attention needed for updates. Depending on the geographic location OSM may have the most detailed maps or the most bare/outdated map.
Con Very slow 'search' and 'route calculation'
Probably because Maps.Me has more POIs in its database which ends up with all searches and route calculations being very slow.

Does not show images offline if supplied in standard kmz file. i.e. zipped kml plus image folder.
Con Offline images
Does not show images offline when imported in classic KMZ file, i.e. zipped kml.doc plus image folder.
