I did testing of both sniffjoke and obfsproxy with Tor this summer. [1][2] I had trouble getting sniffjoke to work reliably enough to actually test its properties against DPI attacks. I found obfsproxy to be reliable, but at that time it was designed to work against only some of the known DPI attacks and therefore did not protect against others. I also tested my own protocol, Dust [3], which at the time covered more DPI attacks.
I'm sure a lot has happened since the summer on these projects. The developers of both sniffjoke and obfsproxy are very nice and I'm sure they would be happy to answer any questions you have directly. The last I heard, Vidalia integration has indeed planned and there was already a plugin for configuring obfsproxy.
