Reports in rails app


I am looking for some reporting library for rails.

Does anyone have experience with such libraries, until now I have found * Ruport (Ruby reports) ( * reportable (GitHub - saulabs/reportable: A plugin that makes basic reporting for rails models dead simple. Formally known as reports_as_sparkline.) * ReportBuilder ( * dynamic_reports (GitHub - wayneeseguin/dynamic_reports: Dynamic Reporting Engine for Ruby && Rails)

The most recently maintained project seem to be reportable. But ruport and dynamic_reports also looks like reasonable projects. ruport seems very featurefull

Please provide some experiences and comments.
