I preferred the KHOMO over the Jettech when I had both for the 9.7. The KHOMO covered more of the chamfered edge and seemed to attach more confidently. The ESR is nice but is a different beast. The back is solid plastic with a silicon rim, but it was the case I could get quickly and I'm waiting for them to release the smart-cover-compatible back case for the 10.5

This is the ESR I have for the Pro 10.5 in black (which doesn't seem to be available right now)
