What do you like best?
PowerBI feels like and enchanced version of Excel.
It is awesome for data visualization, since it allows us several options in terms of presenting Data.
More than that, it also has some functions, just like excel, which makes it a very complete software.
What do you dislike?
Sometimes it could be more flexible.
For example, we are not allowed to edit data directly on the sheets, which makes it hard to clean a database. Due to that, it forces you to have something else, like Excel, to help you clean up a database before you start working on it on Power BI.
Recommendations to others considering the product
If you are having trouble working on presentations and ways to show your data, you've gotta start using Power BI.
What business problems are you solving with the product? What benefits have you realized?
Essentially Data Visualization. Since SPSS, my main tool for data analysis, is not great in that specific field, I complement it with Power BI.
