Gow is a lightweight tool that enhances Windows command line with essential Unix commands, primarily focusing on Go development, whereas Cygwin provides a full Unix-like environment on Windows, supporting a broader range of applications and scripting. While Gow is faster and simpler, Cygwin offers more comprehensive Unix functionalities at the cost of performance overhead.
