Once you get to ISO 800 the W80 again produces images with a little more immediate appeal, but there's really little to choose between these two shots that doesn't come down to aesthetic preferences. Our experience of ISO 800 in real world use was that the loss of detail and contrast - and the visibility of the noise itself - gets progressively worse as light levels start to drop. That said, as we've seen before with this sensor, for such a tiny CCD the output is surprisingly usable in better light for smaller prints and less demanding subjects.

It's also worth noting that the W80 has chosen an aperture of F10 (we noticed this in real world use too - surely a higher shutter speed would be more sensible), though since we've no idea if this is a 'real' aperture or an ND filter we cannot comment on whether this will cause any issues with sharpness due to diffraction effects.
