Actually it was addressed, but if you'd like a more complete and total debunking of this nonsense, ok - sure. It's not like it will really matter, as you will only see what you wish to see.
The more you say things like that, in advance of what I say no less, the more I am convinced you are talking about yourself.
Even on the objective sensor tests the difference between a D3100 and a T3 when it comes to high iso/low noise is only about 0.3 Fstops, so not a huge difference between the two really. So when we examine your incredibly subjective testing methodology used over at DPReview, we really shouldn't see a huge difference between the two images as far as noise. I wouldn't expect there to be - nor would anyone with an ounce of objectivity.
I'm unclear what's subjective about taking identical photos in fixed conditions with both cameras. That would seem to be pretty near the definition of objective.

The D5200 is just as out-of-scope as the 6D is.
They are posted above. Black seems debatable, but every other photo seems to go strongly in favor of the T3.
