In Britain and France, OSM is very good. In NL and DE, it is amazing. In the US, it is okay.
It sort of depends on the user community that edits it. OSM is used heavily by the cycling community who want to put all the off-road cycle paths and so on onto the map. And it's used by hikers and wheelchair users and a bunch of other subcommunities who want to make it good for them.
In the US, there isn't such a big community of fanatical cyclists and so on, so less need for alternatives to commercial maps like Google and Apple.
As for Street View - give it a few years. Mapillary is building a Creative Commons-licensed, user generated Street View. http://mapillary.com - example: http://www.mapillary.com/map/im/SX2UBibwT4S1h4u_jSHmxg
