The feature that I have found to be the most valuable is the ease of deployment.
WebLogic Suite integrates seamlessly with Oracle Database and other Oracle products, offering excellent scalability and centralized control over services. Its robust transaction handling and outstanding performance make it a reliable choice. However, licensing is expensive, and support needs improvement. Lacking connectors to external applications, it requires significant expertise for tuning and has inefficient restart capability, taking 15 minutes. Despite these drawbacks, it provides strong technical support and integration capabilities.
