Microsoft Power BI vs Pentaho: Which is best for you?

Power BI provides good value with easy-to-use dashboards, rapid deployment, and a clean UI that enables our editors to view submission patterns, reviewer response time, and publication schedules with little training investment.

The customizability of the charts isn't as rich as in Excel or Tableau, and you need to understand how to model the data if you're dealing with multiple datasets and build relationships between them accordingly.

Very easy to learn, provides efficient report designing tool and integration with different datasource is too good.

Interface is not intuitive. If you want to solve the problem by yourself there is no much information how to do that even with a very small problems.
