Ask HN: Google Maps vs OSM in countries like India

Hello everyone.

I am making an app which will be using a map service extensively. Now Being an open source enthusiastic, I want to use Open Street Maps as it is open and also highly customizable.

As my app will be focused towards the Indian audience, Less open data on Open Street Maps for India like countries has made this decision hard for me.

Here is a comparison to see how less details OSM has. http://tools.geofabrik.de/mc/#14/30.7125/76.7832&num=4&mt0=mapnik&mt1=google-map&mt2=bing-map&mt3=mapnik-german

Any suggestions on how can we use OSM and still have extensive data ?
