This webcam actually has WORSE low light performance than the c920, and far more ISO. It also has a feature called RealLight 3, which cannot be disabled and will apply a post-process filter in attempt to correct the light. In reality, it smooths over too many details and flattens the light out. If you don't have studio lighting, this camera will look bad, much worse than a c920 due to a noisy image. If you DO have studio lighting, this camera will produce a cleaner image, but you will likely have a washed out colours that look like your shooting in the wrong colour space due to RealLight 3. It has a myriad of technical glitches and bugs which I won't go into. Even after 8 hours of fiddling with settings I'm not happy with the image, and the c920 remains more consistent in quality across most ranges of use.
