Among Cisco 3560 users, this specific release (15.0(2)SE11) is widely regarded as a pinnacle of stability. Later releases on the 15.2 train introduced feature changes and memory constraints, while earlier 12.x releases lacked modern security patches. SE11 represents the final, highly mature build of the 15.0(2) family.
