Incredible clarity, wide enough aperture for natural light indoor photography, lightning-fast autofocus (milliseconds on the 7d II), and only a 10% mistake rate. Although this may not be a major issue for video, the electronic, highly smooth manual focus makes it theoretically hard to fast get into focus. The vignetting and HA that occur up to f/ 4 can be eliminated with a single click in ACR. It's a steal at the price they're offering! The 50mm Canon 1.4 that I used was an older model, so its sharpness and autofocus speed weren't particularly impressive to me. The image quality is many times better than that of the whale 18-55.
