The CD:NGI imagery is the official imagery but currently a bit out of date. In places Bing should be more up to date and for some locations like Cape Town I believe more detailed imagery is available.
The biggest "missing" thing that I have personally experienced is lack of speed restrictions and lane information on bigger roads ( highways ) not being properly mapped. So it would be tagged as a high way but would not contain information about 2 lanes or 3 lanes and offramps/onramps can sometimes be inaccurate. In cities the speed limit is 60km/h unless indicated otherwise as being 40 or 50km/h. On highways the speed restriction is 120km/h and on rural roads 80km/h unless indicated to be 100km/h There is also a lot of missing road names.
