This largly depends on the location you are referring to. In many german places / cities, OSM data is often more accurate than Google Maps, even for commercial infos like opening hours. In the end it is up to people to ensure data is up-to-date. Apps like StreetComplete can help with that. Organic Maps also allows for some editing.

I much prefer Every Door, especially for updating opening hours and any kind of place details. Have you tried it?
