Comparing Terra Server and Google Earth

Terra Server images seem a bit dated - I'm guessing 8 to 9 years since the last aerial fly over/update, based on known images. T.S. offers b&w images, most Google Earth are in color. Both offer "roof top zoom in" but Google Earth doesn't have near the database for this type of image. Google is more current, but not 100% capable of image "zoom in" - you get a fuzzy map in these cases. Both will get you within 300 meters of a destination or target. Google has a better street and road grid capability. Google has a "terrain tilt" feature, but the 3D images seem distorted - but, this feature is cool when looking at big buildings in cities, landmarks, etc. Pretty cool stuff.
