I couldn't get SuiteAnalytics Connect to run reliably. It timed out on long queries. That being said, Tableau was kind of nice, but it's problematic with reproducibility, because it's not transparent how you built something, and it's not as fine-controlled as real SQL.
Ultimately, we ended up using suite analytics connect to simply clone the netsuite database into a local PostgreSQL database, and we have Metabase interfacing with that, our legacy database and our website database
