Yeah, it makes me sad how people actually enjoy feeding a proprietary data silo instead of providing their knowledge to everyone for free in open projects.
Best is in the eye of beholder. As for amount of detail, accuracy, speed of updates and speed of response to such vandalism, OSM seems much better to me (at least judging by its European coverage, don't know how good it's in your location). No Street View? That's acceptable for me.
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.
