Open Street Map - good for hikers/bikers/anarchists, BAD for people who actually want to look up their address. It really is a nice "map your own" kit, but in no way shap or form beats google maps, unless you are some anti-google bloke, then that explains it all. It does not "blows away" Google Maps by any stretch. Until Open Street Maps has their own street mapping cards, satellite telemetry, Traffic information, navigation with voice/reroutting/guidence, and detailed area information, then no, it does not. I love FOSS-like projects, but come on.
