Haiku is a lightweight operating system designed for personal computing and is heavily inspired by BeOS, offering high customization and multimedia support. TrueOS, based on FreeBSD, is more suited for server and enterprise environments, with strong security features and robust package management, making it less user-friendly but more stable for various applications.
