I’m looking to never have to use Google Maps. Is OsmAnd+ the best?
I have found OSM data (and therefore Organic Maps) more up to date than the others, at least for roads. In the past six months for me that was three different cities, and two different countries. Small sample size, but including my city there were several places that google had not updated for years.
As for your city to OSM integration: OSM does not take data dumps. But your city could encourage people to update the data in OSM or better still leverage OSM as a data truth and curate it, and load ArcGIS datastores from it.
You can help using Street Complete which is a very easy to use android app that fills in the details of whereever you are at: Is this road paved? What are the business hours here? Is there street lighting? etc.
