Now for some comments comparing RS and CR.
I see RS as a developer tool. The VS IDE is just too complicated for user based report design. So I see CR as superior in ease of use, and in power/complexity. The things you can do inside the formula editor with variables, User Function Libraries, are light years ahead of RS.
And as for the parameter pick list mentioned above. There are third party solutions out there that do this now (inlcuding my own cViewPICK utility), and CR11 due in January will do it as well.
In addition, Cr does some neat things with parameters like ranges, multiple values, no upper bounds. This is because the parameters are processed before the SQL is generated. With RS, the parameter are part of the SQL so multiple values and ranges will never be available.
If you are a developer working on an app it might be tempting to use RS for your reporting needs. But allocate some time to deal with all those user requests for new reports and report changes.
If you are a developer thinking your users will never want any new reports, think again.
If you are a user, CR is the better tool
