GnuPG is primarily focused on secure communications and offers strong encryption capabilities with robust key management, but has a steeper learning curve. FreeOTFE, on the other hand, is designed for ease of use, particularly in full disk encryption and file management, making it more accessible but less versatile for advanced encryption needs.
