Microsoft Forms Pro has more robust tooling to support deeper analytics and insights with integration across your tools, such as Common Data Services (CDS), Power Platform and Dynamics 365. With Forms Pro, you can send branded surveys to customers with your company’s look and feel. Surveys are simpler to distribute across email with embedded experiences. You can automate sending surveys with Microsoft Flow and leverage preconfigured flow templates to integrate with Dynamics 365 apps. Sorry we do not have feature comparison.
