DXOMARK, um, forgot to review the entire XZ2 line, including the XZ2 Premium, which I suspect would have outperformed the XZ3.
The problem with their benchmarks is that they don't weight well for typical use cases. I agree, Sony's sensors have fallen behind, and they don't handle extreme shooting requirements as well as certain phones; however, a typical smartphone user who isn't specifically seeking those specific conditions may notice the difference one out of every 300 shots. I haven't experienced the highlight clipping described by DXOMARK, though I am using a higher-end model than the one reviewed.
I've been shooting with my XZ2 Premium since August, and have gone so far as to take side-by-side shots with the latest Samsung and iPhone models. Generally speaking, the Bokeh is better on other high-end devices. However, the high saturation in low light (a detriment in the benchmark) actually creates visually appealing images with a wider spectrum of colors compared to an iPhone taking the same shot. I have only experienced unusual chroma noise in night shooting, but my night shots also end up sharper than others'. It's easier to correct the noise than to sharpen an image, so I'm okay with it.
I'm interested to see what the Xperia 1 scores later this year, since it's the closest yet to a successor to the XZ Premium and XZ2 Premium, neither of which were scored by DXOMARK
