I have experience with Power BI. Whether one or the other is better depends on the organization. If the organization is using the Microsoft cloud, then they should proceed with Power BI, which is easy for them to maintain and offers one platform for all the solutions. 

However, if the organization has multiple platforms like Oracle and Microsoft, then it is better to go with a third-party solution for BI. Otherwise, it will be very expensive to integrate. That's why we use Knowage and Spago.

Before Knowage we were using SpagoBI. Aside from that, we're also using Power BI, however, with the costs related to Power BI and the flexibility, Knowage is way more affordable. With Power BI you are looking at $10 a user. With Knowage, if you can get the dashboards right, if you can implement reports properly, then it doesn't cost you a thing.

I did not previously use a different solution; this was the my first BI project.

I previously used Tableau, Qlik, and Power BI. SpagoBi was a choice imposed by the company (financial reasons).

No

This was the first time we were going to use a BI suite.

I did not previously use a different solution.

We didn't use a previous solution. Since SpagoBI was originally created by my company, and we still support it, the choice was easy.

Yes I did, to try new and improved version of SpagoBI.

We used SAS Analytics.
