I have Axioms.
The Performance ones are better, but alas, no more. The Axioms have a hard reinforcement (as they should), which is screwed to the attachment hardware through from the outside. The screws are covered on the inside by by little rubber caps which easily dislodge and disappear, leaving the inside of the bag full of sharp metal snag points for clothes and what-have-you. They might be flattened off machine screws, but they still catch things, including my knuckles when I'm getting stuff in and out.
