There are two beings. One is human, and the other is a fake, pretending to be human.
The fake does such a good job at pretending to be human that is indistinguishable from being a human.
Which, then, is a better human?
There are three trains of thought.
The first is simple, straightforward, black and white. A human is a human, a fake is a fake. No fake can ever be as good as a human.
The second sees beyond this. If the human and the fake are indistinguishable, surely they are both equal.
And the third - the third view. The fake is of far greater value. In its deliberate attempt to be real, it's more real than the real thing.
Nisemonogatari had some wonderful quotes, and I feel it really applies here.
