Power BI is a managed Microsoft service built for interactive data exploration and visualization and it supports collaborative report creation through the Power BI service where users can share workspaces, publish apps, and comment on reports. The platform includes authoring tools and cloud hosting so teams can iterate on visuals and dashboards together and share insights with stakeholders.

Azure HDInsight is a managed big data platform for Hadoop, Spark, and Kafka and it is focused on processing and running analytical workloads rather than providing an integrated interactive visualization and collaborative reporting environment.

Azure Data Factory is a data integration and orchestration service used to build ETL and ELT pipelines and it does not offer end user visualization or collaborative report authoring capabilities.
