I have also tried Metabones for video with Canon glass (both modes), it does not work properly, so I agree. These videos fool people mostly. Can use metabones in green mode for stills with center AF for stills for not to fast photos shooting. Landscapes are ok.
The problem with Sigmas is that they make noise when your AF works hard e.g. sports. A lot of Canon glass also make quite some noise.
The best lenses are Sonys, most of them are quite when AF for video.
Not my experience, in fact, I fully disagree. Metabones (version IV od V) works better than MC11 for _stills_, esp. in AFC. The Sigma adapter is restricted to the central portion of the VF, whereas I can use eye focus and tracking over the full screen with Metabones (green mode). Performance is not as good as with native glass, but very close. Many modes are fully supported. This is consensus in all the different forums I look into, too.
