I am looking for feedback from people who are familiar with both TerraGo and Esri's respective geospatial pdf functions. I understand TerraGo offers a broader spectrum of functionality, but wonder if TerraGo's enhancements have been worth anyone's while.

I don't really like to dis them. But I haven't had much success getting it implemented.
I think the first question you need to answer is. Absolutely you cannot accomplish what you want to accomplish without pdf.

You need to make the toolbar easily accessible for install and teach how to useit and for what.
Then I think all the other stuff can be worked out.
