I don't consider they are same quality as long as the leather thickness is different.I actually called and they checked with the product managers and in fact it is the same grade leathe; it is just cut thinner. So no less quality at all!
Thinner means normally 1 piece of cawhide can be cut to 2 piece lather, (cut to 2 layers). the normal rouge stitch pebbled leather with a thing suede leather. while suede rouge is only one single piece of leather, the exterior side is made to suede texture and another side is smooth. This single piece suede leather is almost as same thickness as normal rogue which combines 2 layers of leather together. it's indeed better quality.
