I have some experience wearing both types on shoes and watch bands. leather with the Feather marks (called: Quil hide or body skin) is a zillion times softer than the leg leather actually may be the softest leather of any animal skin. Ostrich skin is very flexible and both types are very strong, If you are used to thick Cow leather straps the Ostrich skin may feel weird. Its flexibility, thinness, and softness will make the strap feel more like it should be on a small dress watch instead of a large sport watch. The Leg leather is a bit thicker and harder and i heard its much more durable than reptile skins...not sure how true it is. It is a off beat choice for a watch strap for sure! To me the leg leather always looked like a cheap croc wannabe but the feather skins stands out and looks more luxurious than most any other skin (string ray or horn back are also nice). I would recommend going with a strap that has dark stitching instead of the white in the picture you posted, the white kill the feather marks which is the point of the leather.
