DataGrip added value compared to IntelliJ IDEA
I am Max, the PMM of DataGrip.
We usually say that DataGrip provides the same functionality as all the other IDE's from JetBrains with the database support. As mentioned above, DataGrip provides better user experience as a standalone IDE.
From FAQ part from this blog.
Does DataGrip repeat the functionality of the database tools in other JetBrains IDEs?
Yes, the first version focuses on that core functionality.

This repeats the functionality in Intellij, but does it add any more features over and above Intellij? If they are equal right now, will that always be the case? Would be nice to see a feature comparison chart.

The latest version of IntelliJ IDEA Ultimate includes the functionality of DataGrip 1.0. Still, DataGrip is focused on working with databases and SQL and thus may provide better user experience as a standalone IDE.
In 2016.3 there's a feature that is DataGrip specific
Tracking database changes
If there are lots of changes in many places, you can see all of them from the Database Changes window. Important! This window is available only in DataGrip, but not in other IntelliJ-based IDE's.
