Google Maps almost without exception kicks ass of all other mapping solutions almost throughout Asia - this includes Bing, OSM, Nokia and Blackberry maps. Even in a handful of countries where other maps are good, Google Maps still beats them with their local business information.
OpenStreetMap has superior information for my city (Montevideo, Uruguay), especially housing numbers.
Though for businesses and such, Google Maps is better (and I like the maps and the way they render, too).
This thread makes me want to resurrect one of my side projects (mapping apartments for rent and for sale, the Craigslist equivalent here is lacking on several points, although it is better than Craigslist).
Yup, Taiwan as well. I contribute to OSM, but still got to say, it is utterly useless over here, while Google Maps have pretty much everything plus local quirks covered.
