Snapsort ratings can be silly, but the comparison of features between cameras can be useful.
I agree that the "advantage" cited is often silly. I don't like cameras that are too light, so the "advantage" does not go to Sony for me. I want the narrower field of view of the smaller DX sensor for my wildlife shots. So, again, the "advantage" of Sony's larger sensor does not apply to my application.
Still, things like battery life, viewfinder type, number of focus points, number of lenses available, extra SD card slot, and built in flash are all things that are important to me and would rule the Sony out for me.
If I felt I had a problem with image quality or noise at high ISO, I guess I'd be looking around. The D7100 does just fine for me in these areas, though.
Now, with video, I simply can't give an informed opinion. I have never even used the video on any of my cameras. So, again, that's a feature that may make a big difference to many, but is something I could (and do) live without completely.
