Toad and the tools offered by Method R are not mutually exclusive. Many Method R customers are also Toad users.
Method R is a way of thinking about the process of optimizing. That process involves measuring the response time (the ‘R’ in “Method R”) of individual experiences that users have with your system. Toad doesn’t provide that capability.
Unfortunately, Toad doesn’t offer a framework for third-party extensions like Oracle SQL Developer does. We would love to have a Method R Trace extension for Toad, but their architecture just doesn’t permit it.
