I switched from Sony A6000 to M10 and love the camera. My main reason for switching was the high cost of E-mount lenses compared to the M4/3 format. As another review notes, this might not be a very compelling upgrade if you have the Mark II version. However, if you're new to Olympus, this is a great camera. Although it's a 16MP sensor rather than Sony's 20MP sensor, there's no noticeable difference in image quality in practical use.
