We do not have that sort of collateral drafted yet, but it is something we would like to be able to offer folks such as yourself. Real time results are something that jumps out at me with respect to Full Contact. There are times where they do not have the record immediately and that can hinder some businesses depending on the use case. The added data-points offered is also something that stands out to me with respect to both. Perhaps the carrier or line provider data is important because you may need to know if a phone number is a Google Voice number. Or if you are looking for address and some bit of social data such as hometown or education, that might be a combination you can only find with EveryoneAPI.

As I mentioned we will be working to develop some collateral to that end. After well over 10 years in the data space I would say that the best way to compare is to do a batch > 1000 records head to head. :)
