Why do people prefer Criterion or Shout, Arrow, Kino Lorber etc?

[Movie shy]

Hi,

Just wondering why people prefer Criterion or Shout, Arrow, Kino Lorber etc. over a regular release of a film? I have Criterions and I like the extra special features you get and the packaging but for some films I am fine with my regular blu ray’s. For instance I love the film “All About Eve” and have the digipack that I got for 5 dollars at Big Lots a few years ago. The video is great and love the special features so no need to get the Criterion. I have “The Phantom of the Paradise” on Shout and am impressed with all the special features. I just wish the independent labels didn’t charges so much for films. Even with 50 percent off Criterions at B&N at 20 dollars a film that still seems expensive to me. I realize some labels will only have a limited number of printings so the price needs to be high but many times a regular blu ray will suffice. Any thoughts?
