I have a Red Hill Tactical (actually two of them, I liked the RH competition holster well enough to get a retention holster for 3-gun), and I have a Dara.
The RH is nicer but the Dara is possibly little more secure, but not as good of a fit. I had to mod the Dara slightly to take the SRO. Dara was quick ship and the RHT takes a few weeks. The RHT accepts standard belt attachment patterns, the Dara does not.
