Tor is primarily a desktop application designed for high anonymity and access to hidden services, while Orbot is a mobile proxy application that provides Tor access on mobile devices but lacks direct support for .onion sites. Users looking for robust anonymity and access to the deep web might prefer Tor, while those needing mobile access and ease of use might opt for Orbot.
