I don't know why anyone would look at pictures that aren't done by a professional for a comparison. There are so many things that could make it look off if you don't know what your doing it ridicules . For example was the camera held or on a tripod? If it was held it and you move the tiniest bit (like when you press the button) it will be off compared to one that you manage to not move on. Lighting is also big and if you don't know what your doing the shots can look terrible. And what if the picture taker is just plan bias? He/she could easily make one look worse than the other.
I think a lot of people out there are thinking they are going to be photographers just becasue they have an 8mp camera. You still have to know what's up to do good pictures. If you compare them you have to put them all on a level playing field like in a tripod same distance same light same time of day etc etc. I have yet to see or hear how the test comparison pictures were done and what the setup was.
So if your not pro photographer these camera are more than enough for the casual pictures taking, that most of us will be doing, and if you're a pro you aren't going to be using a phone camera.
that's my .02
