We decided to go different ways during the design of our cloud storage networks:
• UU does not bundle metatext/Descriptions, pictures to the content (like container solutions e.g. MegaNet). In order to deactivate fakes faster and more secure, 3rd-party services allow user comments for each content. The community can add as much meta information (crosslinks/ bundlings) as necessary to any given hash-id/unique file.
• Download and reupload of content under different id and different beneficiary of payment is not possible in UU. Lifetime guarantee for uploader, first come, first serve.
• In UU the uploader sets his price as well as the publisher (website owner), where a link is published.
• Reassigning content-payment target to copyright holder/claimer/take down abuser/copyright trolls is not possible for technical reasons. There is no human interaction in the whole process, no single point of human legal decision for different legislatives. Once a file is dumped in the deep deep space of IPFS-peer to peer cloud storage kernel, its public for anyone to use. About Details of deleting or revoking files within the IPFS system see there.

• More differences are likely as both systems are under development and can not yet be compared seriously.
