I've tried a number of ergonomic mice including OP's pic and picrelated and began to develop severe pain. I found that all "ergonomic" brands use trash buttons which require significantly more force than gaming mice (especially the scroll wheel buttons), and that this was the greatest source of strain. Go with whatever mouse is comfortable and has the softest buttons; this fixed all my hand issues. Gaming mice tend to have very high quality/soft switches; I think mine uses Omron switches.
