I’m having similar thoughts. I’ve decided to buy a new compact camera, but so far I haven’t been able to decide between Sony RX100 M3 and Canon G7X. (I’m not sure if you’re looking for a "pocketable compact camera" or if you are more into mirrorless options.)

Both of these seem to be really good options, and overall I consider them more similar than different. The Sony has a useable viewfinder which I would really like to have. The Canon has some more reach and a bit better maximum aperture across the common focal length range…but no viewfinder. The Canon is also a bit less expensive. I consider other differences (that I’m aware of) between them as "minor". I.e. for me the question is if I want the viewfinder so badly that I’d be prepared to pay some more and still get some less focal length?
