It seems intended to be more anonymous and decentralized than Tor, and safer thanks to the strength of numbers, but their whitepaper is diseharteningly incomplete and disingenuous, particularly about problems that are shared with Tor.

For example:

"The distribution of Entry Nodes is a difficult topic. If oppressive governments are able to access this list, they will block user’s abilities to access the list."

Or simply, you know, go after whoever runs entry nodes. Or run their own entry nodes and, even if they can't compromise the network, trace the evil cypherpunks who want to use encryption.

Unfortunately, some practical and political problems cannot be solved with improved cryptography.

There are a number of differences (which one might say would take an entire whitepaper to describe ;P), but as one high-level and in my mind very interesting example, Tor actually is a centralized service where nine directory servers are able to decide the state of the network; we are accepting nothing less than a fully-decentralized system.
