Okay, but why is it better? Before I read the whitepaper, I want to know what I'm looking for?

Comparison to TOR: Short paper: http://www.cypherpunks.ca/~iang/pubs/SphinxOR.pdf Longer paper: http://cacr.uwaterloo.ca/techreports/2009/cacr2009-33.pdf

TLDR: "Our new circuit constructions are also secure in the universal composability framework, a property that was missing from the original constructions. " "Importantly, the circuit construction messages for these new protocols are significantly smaller than those in the original protocol and there is no addition to a user’s computational cost. " "Therefore, our Sphinx-based design achieves the same security guarantees with much smaller messages."
