In this case, DXOMark magically added a metric (bokeh and zoom) just one week after the iPhone 8 review. Of course this is a good plus for Apple. Before iPhones were behind Google Pixel, behind HTC U11, Samsung S8+. They were not in the top 10. Now magically, they get to be on top. I wouldn't be surprised if there wasn't a discussion or collaboration between doxmark and apple to review their metrics to have iPhone 8 and X under the best light possible
Pixel v iPhone 8+
90 - 89 : Exposure and Contrast

98 - 74 : Autofocus
70 - 64 : Texture
65 - 68 : Noise
50 - 73 : Artifacts
81 - 84 : Flash
24 - 51 : Zoom
30 - 55 : Bokeh
91 - 89 : Video
I guess picking the "best" comes down to how important those features are to each customer. Though Google isn't standing still, the Pixel 2 is announced in two weeks.
I think the scores are fairly registered but they tend to bend a bit when it comes down to money. Google (and their fans) shouldn't complain if they did the same trick before.
I think the iPhone 8 Plus has a really great camera and the numbers show it. Though the importance of bokeh and zoom is something that you can debate. But I like the pictures that the HTC, Pixel and S8 take a lot as well. For me personally having optical zoom is a killer feature and definitely the feature that nudges me into the direction of the iPhone 8 Plus.
