I work at SmartyStreets, where we've learned that geocoding is very, very difficult, so I definitely feel your pain! We started with basic Census Bureau stuff and it's definitely complicated, and accuracy can be spotty. (We've since worked with other data vendors to improve the accuracy.) It's too bad we don't all have little cars to roam the country with and manually collect rooftop-level data like Google does.
