For me, better than the competition, ...

... As long as I am able to tell.
I have known and SunSniper Blackrapid products never tested, however, the not quite as famous hugu used for a while.
All three products do not interfere with the attachment to the tripod connection and thus in particular the position of the camera,
when she hangs upside down from the hips.

The loops can be quite good thread with a little skill in my EOS 70D, at a pinch you take ne small pliers to help.
Very nice: Stuck to the camera from the strap so the Schappverschlüsse not mind if you build the camera on the tripod for example.

I have particular reason for purchasing this product, because anytime I can adapt to my needs the camera attachment. With the OP / Tech Supper Classic strap the camera can sometimes quite usually be worn around the neck,
or I use the latter without shoulder to tinker an attachment to a backpack or belt pouch.

On the camera, I have mostly a small wide-angle or a 50 fixed focal length - at least when I'm traveling.
Heavier lenses (24-105, 70-200) I usually fix still with the extensions on the belt to protect the bayonet.
Here like a screw as SunSniper or Blackrapid offer advantages.

The shoulder pad is super comfortable, the belt fits if necessary even under the jacket, all the snaps are stable and act fairly dibasic.
However, the pad smells at the beginning a little bit - but has given quickly.

Conclusion:
I am convinced of the OP / Tech concept. Who moves around a lot with the camera, sometimes for several days with backpacking is and flexible conversion options estimates, this belt should keep in mind. With respect to processing and material, there is little reason to complain.
