That's a nice write up linked :t:
A friend of mine just bought the Sony RX10III and we learnt a thing or two from reading and luckily for him a one week trial period before purchase.
1. As mentioned in the review, the Sony can extend to 900mm at 10MP, or 1200mm at 5MP optically in Jpeg mode. Add this to the fast high quality lens, and 1 inch sensor and there is wonderful unmatched subject isolation (through combination of telephoto reach, depth of field and nice background blurring) until you get to APS-C or FF sized sensors.
2. Autofocus and image quality is superb for the sensor size, and in comparison to larger APS-C cameras. See a very informative write up by long time industry tester, Ken Rockwell (who gives it very big raps) here:

3. One of the most important things with P&S zooms or Bridge cameras is the startup time, and the zooming time (in the absence of manual zoom), as well as fps and buffer size. The Sony is good in this regard and highly customizable to boot.
The extra reach of the Nikon comes at the expense of smaller sensor, slower glass, less background isolation, and less flexibility on moving targets. Everybody needs to try for themselves where possible, though the Sony does seem to be a standout product at the moment. Further reports here:
