Which camera has better image quality between sony a5100 and canon g7x mark ii? Considering only the quality of stable pics, all else equal.?

The G7 is a 1" sensor. The A5100 is an APS-C sensor which is physically larger than the 1" sensor and will have slightly larger pixel sites than the G7 sensor. Thus, the A5100 will give slightly better technical image quality. Another thing in favor of the A5100 is interchangeable lenses. Both cameras can be operated using manual exposure. In the hands of an experienced photographer, they will put out about the same image quality, however, the A5100 would be a more versatile camera due to the interchangeable lenses. Do you want a pocket camera? If so, the G7 is an excellent choice. The A5100 doesn't have a retractable lens, thus, not suitable for pocket storage.

You'll get the same picture no matter what camera you use. Image quality depends mostly on the photographer's skill. The camera is only a tool. As a tool however, expect the mirrorless camera (a5100) to offer more control making it more complicated to use beyond Auto mode compared to the advanced point-and-shoot (G7x Mk. II). In Auto mode, they're practically the same.

There's no comparison. The A5100 is an APS-C format mirrorless while the G7X Mark ii has a much smaller 1" sensor. This difference alone means that the ISO performance of the A5100 will be superior to the G7x ii. Here's a comparison: https://www.dpreview.com/reviews/image-comparison?attr18=daylight&attr13_0=canon_g7xii&attr13_1=sony_a5100&attr13_2=apple_iphonex&attr13_3=apple_iphonex&attr15_0=raw&attr15_1=raw&attr15_2=jpeg&attr15_3=jpeg&attr16_0=1600&attr16_1=1600&attr16_2=32&attr16_3=32&normalization=full&widget=1&x=0.16929957168052417&y=1.0482691720672488 Furthermore, because the A5100 is an interchangeable lens camera, you have the ability to use professional quality lenses that will be vastly superior to the G7x Mark ii in sharpness, light gathering (i.e. larger aperture). Plus the larger apertures that are available on the A5100, along with the longer focal lengths that the A5100 must use due to the larger format, will allow you to get a much shallower depth of field whereby you can blur out backgrounds much, much better than what you can do with the smaller-format G7X Mark ii. There really is no comparison between these two cameras. Not only in terms of sharpness, bokeh, and distortion, but in terms of creative capabilities, too. The A5100 is simply a much better image-making tool than the G7X Mark ii could ever be.
