With a Photo score of 101, the Apple iPhone X achieves the best results so far for still images, edging out the Huawei Mate 10 Pro and the Samsung Galaxy Note 8, the previous joint leaders in the Photo ranking, by one point. Compared to its cousin iPhone 8 Plus, the X improves noticeably on Zoom performance, but also does better in terms of Exposure, Color, Texture, Noise and Artifacts. Other key strengths in still image mode include very good exposures and HDR images, accurate color rendering, good detail with low noise, as well as a natural-looking bokeh effect in Portrait mode.
So it's the best for stills at a 101 rating but conclusively, DxOMark rates it 1 point lower overall than Google's Pixel 2 / 2XL due to it's Video Performace. Once again, it's all subjective. As always, the best camera is the one you have on your person.
