The P20 Pro's night mode is arguably better than the Pixels. It is sharper, works in worse light, and has more natural colours. You also seem to be confused into thinking that DXOMark enables every special mode. They don't. The reviews are overwhelmingly simply the auto settings.
The argument I'm seeing in favor of the Pixel generally is "waves hand {magic AI!}". Sorry, I don't care how much HN is infected by Googlers and Pixel fanboys, there is zero evidence of any magical AI in the Pixel results, and they look absolutely bog standard.
