Any of those with as complete list of local businesses as Google ? If I want to find an ice cream parlor, or an engine oil dealer, or a sports equipment shop in my vicinity , would all three have similar results ?
Google maps is useless for local results form me, I live in a village on the edge of a small town with a few dozen local businesses and 4 chain businesses and all my search results are polluted by 2 cities 30 minutes and 45 minutes away by car, which is really annoying as these results are useless to me as my disability prevents me traveling that far or amount of time.
Probably depends on the area. Where I live, OSM doesn't really have anything beyond just streets. But I've heard other areas have much better coverage.
