Franklin Gauer has posted some kudos based on his experience with
ActiveReports in his post
Why you don't need much more than Active Reports.... In his post he says:
Any programmer with a little salt will tell you the frustration involved with selecting and sticking with a reporting tool. Traditionally, these reporting tools will only get you about 60% (if you were lucky) the way through any project (the actual percentage is probably around 30-40%). Inevitably the user requests keep coming and they end up exceeding what the tool is capable of.
You need to be able to take a generic datasource (i.e. a dataset served up via a webservice) and be able to format it, group it and total it. That's it. And Active Reports does this very well.
In Apolon's Software Torq blog, there is an interesting post about a new version of the MacroView Studio product that describes some innovative use of ActiveReports' extremely flexible end user report designer.
