Actually the full version uses more data, it turns out vectors take more data than jpeg tiles, at lease for urban areas. The big differences excluding 3d features are things like * you can rotate the map * zoom is continuous * the map can be customized on the fly to make it more relevant to your search. So for example a road can be highlighted for one search vs a different road highlighted for a different search. Different buildings/roads get labelled etc. This was all covered to Google I/O when the current version of Google maps was released 4 years ago
