I do like the security features and data recovery for features that were enabled there. With the right configurations, you can maintain an environment without retaining the risk of losing any kind of data. 

There's also a point in time recovery, et cetera. This is quite useful. 

The initial setup is simple. 

It is a stable product.

You can scale the solution as needed. 

It is very feature-rich.

Multitenant has a container database with many pluggable databases. A great feature is that you can upgrade the container to a more recent version and all the pluggable databases are automatically upgraded to that version. Previously it would have required an upgrade for each database. The second great feature is the clone which enables you to get the clone of pluggable databases with one command, as opposed to copying data from one place to another.
