text_parameter vs. data_parameter

In using run_product to call a report are there any advantages to using a data_parameter over a text_parameter?

If a data_parameter based on a record group is passed to a report with only a main query will the report have to query the database at all or will it fetch the data from the record group?

Thanks,
