Ranked in these QuestionsQuestion Ranking
Pro Obtains data from community-based OpenStreetMap
Pro Fast rendering
By using compression of the map data, MAPS.ME is able to speed up the rendering of their maps to one's device. This allows for a quicker feeling app.
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 Very detailed selection of areas to download
That saves a lot of download, e.g. from ~500MB in other applications it is reduced to ~50MB for German surroundings.
Pro Optionally can download traffic information
And showing it color-coded (Google-maps-like) on the streets.
Pro Discover nearby feature
Shows a nicely organize list of interesting places to visit close to your current location.
Pro Matching modern material-like interface

Con No option for satellite/aerial/topographic imagery
Not as useful for navigating while hiking/climbing/etc.
Con No display of speed limit
Neither the next nor the current one.
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.
Con No way to distinguish between fastest, efficient or shortest route
Con Very limited options
E.g. no way to hide certain buttons like the traffic button, or to configure the language used to display city names.
Con Sometimes very strange suggestions
E.g. when not using the suggested route, Maps&Me continues to request to turn even if you are more than 100m after the cross-road.
Con Favorites are a little bit too hidden
Because they are stored in groups.
Con Traffic information is not available in all countries and cities
Source of traffic info is a trade secret this feature is only available to some selected cities.
Con Poor response time to recalculate the route
Con No lane assist
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 Depending on the geographic location OSM may have the most detailed maps or the most bare/outdated map.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 Does not show images offline
Does not show images offline if supplied in standard kmz file. i.e. zipped kml plus image folder.
Con No tourist detail maps
Con Map search is awful
Searching for map files is very frustrating as the map search only shows the center point of each map as a pin, so you can't see whether the map includes a point you're interested in, and since there are usually many historical maps of the same location, they produce many pins appearing on top of each other. You have to download each one and open it in order to see what it will look like, rather than previewing them in the live display. Good overview maps will appear as pins in random locations, while there will be tons of topo map tiles everywhere else
Con Only shows one map at a time
It supports USGS topo maps, for instance, but if you walk off the edge of one, you have to manually load the adjacent map, which is a hassle. It would be nice if, like other apps, you could select "USGS topo" as the map source, and it would automatically show whichever specific map your location is currently near the middle of (since the USGS maps have margins and legends, etc.)
Con Only supports local maps
You need to plan ahead and download a map for each park or region you're going to visit before you go offline.
