I was referring to the 3D models. Personally, I prefer the approach that MS is taking, as it makes cities really come to life. However, on a model-by-model comparison, the Google models tend to look a little better.

I am wondering about the basis for your statement that the Microsoft data is lower quality than Google’s. To be sure the Google DigitalGlobe satellite data is higher resolution than Microsoft’s satellite data, but Microsoft’s aerial imagery is much higher resolution than satellite imagery. If you are talking about the 3D models, Microsoft’s are generated through automated photogrammetric processing techniques that produce models of submeter accuracies. Googles are aggregated from its user community, hardly a means of providing reliable data.
