The Capture is supposed to be used for field work, holding the tablet in hand, while the Feather is a sort of rubbery plastic slip-on case; I'd read the entire thread for discussion on issues like overheating, depending on how much you push your Pro in a case like this.
From what I've used (both Inciprio & UAG), the UAG case is the most rugged case you can get for the Surface Pro 2. I got mine from their site but now I see it cheaper on amazon.
