You can't go wrong with the brands mentioned. When I was looking for an indestructible case a couple years back, Jon Green hadn't rescued Calton yet so I had to decide between Karura or Hoffee. Originally, I was leaning towards Karura but then I thought on the remote chance the fit wasn't perfect, it would be a hassle to ship back internationally. Supporting Hoffee, a US based company was a bonus. That's the logic I used and I suspect that I would have been happy with either. Since that time, I ordered another Hoffee and am extremely happy with the case.
