Power BI vs Looker Studio — Free vs Paid BI Tools

The Short Answer

Looker Studio wins if your data is entirely in Google's ecosystem (GA4, Google Ads, BigQuery, Google Sheets) and you need free, quick reports for marketing or campaign performance.

Power BI wins for everything else — SQL databases, multi-source joins, complex DAX calculations, large-scale data models, scheduled refreshes, and enterprise sharing. It's a professional BI platform; Looker Studio is a reporting tool.
