Other than the ability to automatically generate an interactive documentation for our API using Swagger UI, are there any real advantages of using Flask-RESTplus over Flask-RESTful?
Flask is a highly flexible Python web framework built with a small core and easy-to-extend philosophy. Flask-Restful is an extension of Flask that offers extension to enable writing a clean object-oriented code for fast API development.
Flask-RESTPlus is an extension for Flask that adds support for quickly building REST APIs. Flask-RESTPlus encourages best practices with minimal setup. It provides a coherent collection of decorators and tools to describe your API and expose its documentation properly (using Swagger).
update When reading this accepted answer, consider that there is Flask-RESTX which is a fork of Flask-RESTPlus that is maintained, as an alternative option.
namespace is from the Flask-RESTPlus and Blueprint is from flask to organize your app. the namespaces modules (specific to Flask-RESTPlus) are reusable namespaces designed like you would do with Flask's Blueprint.
I've used both, and the only reason we switched to Flask-restplus was the desire to have auto generated Swagger documentation. In my experience, there are no other noticeable differences. Flask-RESTplus started as a fork of Flask-RESTful, so if you were so inclined, you could read the commit history and see if there are any other noticeable differences.

I am aware of the fact that this answer is probably too late, but it still might be helpful in the future.
According to https://github.com/noirbizarre/flask-restplus/issues/593, the Flask Restplus is most probably dead and abandoned. The last commit was on October 1, 2018. It looks like the project is not being actively maintained anymore.
Therefore, I advise that you use Flask Restful despite the auto generated Swagger docs in Restplus. Since Restplus is not maintained, it is most likely that the implementation will sooner or later go out of date. Rather than switching to Restful once Restplus goes out of date, I think starting off with Restful itself would be the better idea here.
Just my two cents... :)
