Depends on what you are looking for and what country you are in. When it comes to small 'unofficial' roads, bike paths and hiking trails then OSM is much better

Depends on what you are looking for and what country you are in. When it comes to small 'unofficial' roads, bike paths and hiking trails then OSM is much better. When it comes to finding the location of rural buildings, addresses and companies I find Google Maps much much better and complete, at least here in Sweden.
