Control>Query
This method of query allows the user to select system generated queries and customized queries.  It also allows the user to select and input, output, filters, and organize how the results are displayed.

Contacts>Individuals: Advanced Search
Advanced Search allows the user to select the input, but no output.  As a result, this is a more simplified query process.  It will display the results on screen, and allow the records to be batch updated or bulk deleted.
