BlackBerry Messenger, primarily designed for consumer use, offers strong security and a user-friendly experience but suffers from limited cross-platform capabilities. In contrast, Conversations is an open-source app focused on privacy, customization, and federation, making it ideal for users who prioritize control over their messaging experience.
