Thank you, Jenna, this is beautifully written. I went through the same even before Power BI existed, always found it’s more important to have a scalable good working backend, and the tool doesn’t matter as much. But for now, I’d say, the future is open-source, therefore today I’d go for Apache Superset 9 times out of 10. A good read, also including Tableau, is from the founder of Superset: https://link.medium.com/2V94KFKASeb
