I think a lot of people use one type of mapping application that doesn't seem to work for them and then say OSM is not great.

I've had to try a fair few mapping applications that works for me (I can recommend Organic Maps on android)

OSM map data easy exeeds Google map data, the only time I do use google maps is for street view images and satalite info.

Bing is good in the UK because that has Ordnance survey maps - OS mapping data is generally better than OSM (for what I need it for)
