I have found the most valuable feature of Cisco Enterprise Routers to be the simplicity of the command-line interface, it is very intuitive as to how the commands need to be configured for a specific use case.
Cisco Enterprise Routers offer stability and reliability, fostering trust among organizations needing high availability and robust performance. Known for superior security features, they effectively manage large traffic volumes and scale well with business growth. However, high costs, complex setup, convoluted licensing, and administrative demands pose challenges. Desired enhancements include improved support and performance, advanced security, and better vendor integration. Premium support remains a notable advantage due to widespread technician familiarity.
