Could anyone compare the results in cropping a detail using a 1/2,33 compact with about 14/15x zoom vs the same detail using Clear zoom rx100? Could rx100 mitigatey the negative gap of Digital zoom.?

I have a Canon SX230 which has a 1/2.3" sensor, and I have compared it at maximum optical zoom of 14X with the RX100 at the maximum zoom of 7.2X (with Clear zoom ON and digital zoom OFF).

The left image below is a 100% crop of the RX100, while the right image is the same crop from the SX230 resized (about 70%) to match the size of the image from the RX100. You can judge for yourself whether you think the IQ gap is acceptable.
