Re: Google Maps?
OpenStreetMap has much more detailed maps.
OpenStreetMap may have more detailed information than Google, depending on where you're looking. It can also be rather sparse.
Also OSM's maps are not really intended for the general public but as an aid to mappers. The general public are meant to use offerings provided by others which are based upon OSM data. OSM itself has nothing comparable to Street View. Yes, you might be lucky to get a few snaps from Mapillary or OpenStreetCam but you probably won't be that lucky.
I'm not knocking OSM. But the only reason OSM gives a lot of detail around where I live is because I've slowly been adding it myself (and there's still a lot left to do). Some parts of the UK have many more active mappers, others have nobody. OSM is not (yet) a complete replacement for Google maps.
