I have the Normad Rugged on my 11 (No Pro.) I love the case. However, I did decide to go with a screen protector as the edge is not as raised as I've been used to( LONG-time Speck user) up to this point. So far so good. I've not noticed the screen protector picking up any scratches. I have had one drop from around 2.5'. Landed on an edge corner and flipped on its back. Small scratch in the leather, but it has somewhat worn in over the past few weeks. The phone is in my front pocket 85% of the time. I will carry it in my coat when wearing one.
This is my first Leather Case. I decided to splurge even though I purchased a Base 11. I do not like the open bottom design on Apple's cases. Some absolutely love that design however.
I had a Mous Leather Contour as well, but returned it as I experienced the loose fit at the bottom many have mentioned.
In summation, IMO the Nomad Rugged is simply the highest quality Leather Case out there, and is worth the cost.
