Bginfo is primarily a static information display tool that is easy to use and supports multiple platforms, making it suitable for users who want a quick overview of system information. In contrast, GKrellM offers active monitoring of system metrics and is more feature-rich, but is mainly designed for Linux users and might require a steeper learning curve.
