The RX100 II takes really nice pictures. RX100 II produces excellent JPEGs with good color rendition and detail. When you compare image quality from like-sized cameras, it's practically peerless.

The addition of Wi-Fi, outside of gains in image quality, is one of the most notable new features. Wireless sharing is a reliable and useful feature. Connecting a mobile device to the camera takes only a few moments. RX100 II is virtually untouchable in its compact camera class.

Thanks for the info @Vitaliy_Kiselev . Just a heads-up that the last weblink (dpreview) has a quote on it that renders it null. Without the quote it works fine.

Fuji X20 and Sony RX100 II both make excellent choices for advanced amateurs and even professionals looking for the perfect compact camera to carry around at all times

The RX100 II earned an Extremely High rating in overall Image Quality at its lowest sensitivity setting of ISO 100—the same rating the RX100 got at its lowest setting of ISO 80. The resolution of both cameras drops one rating grade once you go beyond their respective minimum ISOs. Given that the sensor in the RX100 II is of a completely different architecture, we were surprised at how close the resolution numbers were. The RX100 II turned in 2280 lines per picture height at ISO 100, while its predecessor yielded 2270 lines at ISO 80. Through the ISO range the two cameras delivered virtually the same resolution: By ISO 6400, the RX100 II captured 1950 lines; the older camera, 1930 lines. The RX100 II lets you shoot at ISO 12,800, where it got 1900 lines, enough for a High rating; the older camera tops out at ISO 6400.

@bassman were you able to install the openmemories tweak on the rx100mk2? I have tried myself but no luck.
