Power BI vs Tableau vs Looker - which should I use?

Power BI is strongest for organizations already on Microsoft (Azure, SQL Server, Dynamics 365, SharePoint) with the best price-to-feature ratio. Tableau excels at complex data exploration and visualization for data-heavy teams. Looker (now part of Google Cloud) is best for teams that want SQL-based modeling with LookML. If your organization uses Microsoft tools, Power BI is the most cost-effective and deeply integrated choice.
