What is the good use for a this vs a standard key value store like DynamoDB or a document db like MongoDB?

Lots of reasons. It supports SQL, you can gradually move data to the in-memory stores, DBAs/Operations teams already know how to manage it and it is well supported. Plus it would destroy both DynamoDB and MongoDB in certain use cases.
