How many of you use Geocoding database for any geo mapping analysis? What tool or third party data service have you use to help with this info?

At the CULytics Summit, I noticed the presentation from Jon Voorhees, had geo mapping from ESRI. Other available known sources are Tom Tom, Experian, Axciom, etc to name a few. Share your choices and what use cases are you using for.
