Axel,
I can give you a comparison against the Hookers based upon this image. I have no experience with your brand.
This set looks as though it utilizes the same rotary buckle. But of course, that is hard to confirm without having both in front of you. I am willing to bet there aren't many manufacturers of the buckle.
With yours, you will need to modify the crotch strap link. You will need to re-stitch it so that there is only a single attach point.
The Hookers have bushings at the attach points for what that is worth. They also have really nice cushions on the shoulder straps.
As far as aesthetics are concerned, the Hookers are custom and you can spec out whatever combo you want. This wouldn't be a factor to you if you want that weekend racer look of your suggested set.
For the paltry sum of $66.88, these differences could be overlooked!
Does this help?
