You can use AdminStudio Tuner to create response transforms and make small modifications to a package via a transform.
In contrast, InstallShield offers a full suite of package creation and modification features. It provides helpful tools you can use to make modifications to the base package or create new MSI packages. You can use it to convert MSI files to MSIX or add more complex functionality, such as custom actions via a transform.
