There hasn't been a definitive comparison test yet. However, if you have Series II L-series lenses, then the Series III TC preserve more of the AF speed of the new lenses, according to Canon.
We're all hoping that the IQ of the 2.0x TC III will be superior to the prior version, but no one has demonstrated that yet.
