I am not too familiar with all capabilities of the Google Data Studio, but from what I know they take a bit more the Tableau approach to defining data sources as results of queries (BigData, MySQL) or sheets data.

I'd say Cluvio would be a bit more fun to use for anyone who knows SQL, the ability to quickly iterate through sql queries to nail down the exact results is quite addictive. Plus the additional capabilities of R make it even more productive for lots of harder cases.
