Intensity Shuttle Thunderbolt vs. Intensity Extreme

Other than the slightly different input connections (component vs. breakout adapter), is there any difference between the Intensity Shuttle Thunderbolt and the Intensity Extreme?
We are looking for a device for Wirecast streaming from a Mac Mini. We've used the Intensity Extreme before, but just noticed the Shuttle Thunderbolt model is $60 cheaper and looks to do almost the exact same thing (take HDMI/component and output to Thunderbolt).
