For Apple Maps this is also country-dependent, since different countries/regions use different map data sources. The turnaround time for regions covered by Apple's own data would be fastest to change, I assume, followed by OpenStreetMap, with third-party vendor (e.g. TomTom) being the slowest. But I don't know how much OSM and TomTom are still used in Apple Maps.
