Which Speedbooster do you BUY for Video? Metabones Vs. Viltrox Vs. Generic ML

Just thought I'd test these three speedboosters I have lying around for Video to compare the differences and see if each are worth their price. Which do you like more? Are the differences negligible? I'd be happy with any of them... My SB Thoughts: Metabones Speedbooster: Good AF/IS Support, Clean, Sharp WO and Stopped Down, Warm Tint, Nicely shaped bokeh. Viltrox Speedbooster: Good AF/IS Support, little rough corners, Good WO and Stopped Down, Neutral Color, Bokeh is pretty good Generic Speedbooster: No AF/Electronic Connection, Swirly on the corners, 3D Pop Effect, Soft Wide Open, Sharp Stopped Down, Bokeh quite rough (but quite helios swirly-like), good if you have a large Vintage Lens Collection.
