4. Ease of Use and Learning Curve
Power BI
Power BI is designed with business users in mind. If you’re familiar with Excel or pivot tables, the transition is seamless. However, advanced analytics may require some DAX (Data Analysis Expressions) knowledge.
Learning Curve:
Easy for beginners
Some learning is needed for DAX and Power Query
Tableau
While Tableau offers a simple UI, mastering it for advanced use (especially data prep) can take time. Tableau Prep helps, but the platform is best leveraged by data-savvy users.
Learning Curve:
Intuitive visual creation
Moderate learning is required for data prep and scripting
Looker
Looker is more developer-oriented. Users must learn LookML for full control, making it better suited to teams with technical data professionals.
Learning Curve:
High if using LookML
Easier with embedded dashboards for casual users
Pricing Comparison (2025 Estimates)
