Shape files or database for offline geocoding
===

I am looking into implementing an offline geocoder module and has looked into [JGeocoder][1] and [Nominatim][2] for solutions. 

So far Nominatim seems to have a more detailed database that if I read correct will be 250GB big and will be able to geocode most addresses in the world. I have yet to try this as the task for the planet.osm data file is still undergoing, but for JGeocoder I was able to follow the tutorial and setup a quick lightweight database which is just a folder with the Tiger files. 

Is there any Tiger files for the whole world? As in is there any Tiger files that able me to geocode any addresses, have went to Census Bureau but its under maintenance at the moment so I can't evaluate the shape file. 

Is Nominatim better in the long run with the support it gives and all? 

Sorry if I post a silly question but I need to evaluate and decide on which to use by the end of the week. 

Thanks
