Tableau is unique for a number of reasons:
To begin, most BI systems are expensive, but Tableau provides a free offering (Tableau Public) as well as a widely used (also free) academic distribution.
Tableau is widely regarded as one of the most user-friendly and adaptable tools currently available, according to organizations such as Forrester Research.
Tableau, on the other hand, is not a comprehensive technological stack like some of the other BI applications; it is mostly used for visualisation and analytics. Other solutions, in addition to Tableau, will be required for corporate data ETL, maintenance, storage, and other tasks.
