Hi;
First a disclaimer, I was the founder & CEO of Windward Studios (but sold it 3 years ago so no present interest).
Big question - do you want reporting, document generation, or business intelligence?
If it's reporting, I think DevExpress is the best. Their functionality is similar to all the others out there but their support is awesome.
If it's docgen then Apryse Fluent (previously Windward Studios). Orders of magnitude better than anything else out there.
If it's B.I. then it depends a lot on what you specifically need. But Power BI is a good one to start with.
thanks - dave
