WixToolset and PACE Suite are powerful tools for creating Windows installers, each with its own strengths and weaknesses. 

WixToolset is a free solution that uses build tools to create .exe setup bundles, .msi installation packages, and .msp patches. However, it lacks extensive functionality for complex packaging scenarios and requires manual changes to XML files, making it time-consuming and challenging to use.

On the other hand, PACE Suite is a paid tool that justifies its cost with a user-friendly interface, extensive documentation, and support for multiple formats like MSI, MST, MSIX, APPX, APPV, and THINAPP. It offers broad functionality beyond packaging, including capturing, analysis, and quality approval, making it a versatile choice for CI/CD integration.

While WixToolset is attractive for those minimizing costs, PACE Suite’s features and ease of use can significantly enhance productivity and efficiency.
