How do you differentiate the quality of a suit?

[Mycroft11Zero]

This question comes to my mind not so long ago when I was asked to differentiate the quality of a few suits. The problem was that I was unable to answer whether which suits were better quality than the others. The only thing I know about the quality suit is the full-canvassing and the feeling of the fabric. I can hardly point out the little details such as those handmade perks. So the question is that how can you differentiate the quality of a suit?

Let's say that if you are to point out the quality of this suit in the pictures below, how would you rank it given that the suit is fully canvassed?

Please advise.

I'm not a tailor, but I am a photographer. Those are not great pictures.

I think our own @unbelragazzo says it best here:

That said, I like to think if you handed me two jackets, I could tell you which one had better buttonholes and superficially better stitching. I also think some of the articles on http://tuttofattoamano.blogspot.com/ can help, especially the ones where the author cuts open old Kiton or Savile Row garments and sort of explains some of the construction technique used, and some of the things to look for in examining stitching and the like.

Unfortunately I cannot. Is there any link that may enlighten me on this subject?
