The Maxxair are easier to install with no drilling into the roof and re-caulking required.
I don't think they faked anything in that video but they would have performed that test with the fan set at its highest speed. So, based on the video, I don't agree that the Maxxair IIs work as well as the Ultra Breeze cover with the fan set at high speed when you're try to achieve the most air flow. But, on a slower fan speed setting they probably would work as well as the Ultra Breeze.
