1. Integration with Different Version Control Systems: FinalBuilder offers integration with a wide range of Version Control Systems (VCS) such as Git, Subversion, Mercurial, and Team Foundation Server, providing flexibility in managing project repositories. On the other hand, PHPCI primarily focuses on integration with Git and lacks the extensive VCS support seen in FinalBuilder.

2. User Interface and Configuration: FinalBuilder provides a graphical user interface that allows users to visually create build processes through a drag-and-drop interface, catering to users who prefer a more visual approach to build automation. In contrast, PHPCI relies on configuration files written in YAML format, which may be preferred by users who are comfortable with text-based configurations and version control.

3. Extensibility and Customization: FinalBuilder offers a wide range of predefined actions and tools to build processes, as well as the ability to create custom actions using scripts in languages such as C# or PowerShell. On the other hand, PHPCI lacks the same level of extensibility and customization, limiting users to the predefined actions available within the platform.

4. Support for Multiple Platforms: FinalBuilder is a Windows-based application, providing seamless integration with Windows environments and tools. In contrast, PHPCI is built on PHP and can be run on various platforms, making it a more versatile choice for organizations with diverse development environments.

5. License Model: FinalBuilder follows a commercial licensing model where users need to purchase a license for access to all features and updates. Conversely, PHPCI is an open-source platform, allowing users to access and modify the source code without any licensing fees, making it a cost-effective option for organizations with budget constraints.

6. Community and Support: FinalBuilder has a dedicated support team and an active online community offering resources, forums, and tutorials to assist users with any issues they may encounter. While PHPCI has a community of users contributing to the platform, the level of support and resources may not be as extensive as those available for FinalBuilder users.

In Summary, FinalBuilder provides extensive VCS integration, visual build process creation, customizability, Windows compatibility, commercial licensing, and robust support resources compared to PHPCI's focus on Git integration, YAML configuration, limited extensibility, platform versatility, open-source licensing, and a smaller support community.
