How does the Easysoft driver compare to the ODBC driver that shipped with InterBase 5.x on Windows?

The Easysoft driver is an ODBC 3.5 driver, unlike the InterBase 5.x driver, and fully supports InterBase 6 and 7 features.

Clients using the Easysoft driver with InterBase 5 and earlier have commented upon its good performance relative to the original InterBase 5.x driver.
