However, there is one VERY important difference: data ownership and privacy. Google Apps for Work (and edu) accounts, which I use for various organizations as well as even for my own personal, single-user domain, have much better data ownership and privacy terms:

Does Google use my organization’s data in Google Apps
services or Cloud Platform for advertising purposes?
No. There are no ads in Google Apps Services or Google Cloud
Platform, and we have no plans to change this in the future.
We do not scan for advertising purposes in Gmail or other
Google Apps services. Google does not collect or use data in
Google Apps services for advertising purposes.
The process is different for our free offerings and the
consumer space. For information on our free consumer
products, be sure to check Google's Privacy and Terms page
for more consumer tools and information relating to consumer
privacy.
