I've got both - the DD gets more use due to its handy 3x3 size/shape, but i wouldn't write off the mil-tec. Its a little smaller and lighter than the DD, and my example at least is well made. I've used it a fair bit over the past 6 yrs or so, and its stood up well. In actual fact, i suspect that the fabric is probably a little more durable than the DD - and its true that the PU coating on my DD tarps is feeling off in a few places - e.g. where it has a tendency to crease in the same spoot when folded into its bag.
