According to reviews, the lens cameras don't work well in large crowds (e.g. Sporting events, your kids' school play). Physically docking to your phone would be more sensible (there's a kickstarter project along those lines). But frankly the gap between cellphone cameras and the rest is closing to the point where 1-3 is a wash, and 4 is pretty crap anyway. So it's 1-4, 5/6. If Sony would produce some decent lens options for reasonable prices...
