I'm fortunate to own both the black Specialist and the new 5" TRP Operator 10mm. It would be really hard for me to pick the better gun between the two of them, but I will say that if I didn't own the Specialist I would probably be ordering the new RO Elite 5-inch to go with the TRP.
The new TRP is just damned nice and doesn't feel like it "only" cost $1500. It feels like a lot more expensive gun. No rattles, no slop, everything just lines up like it's supposed to and nothing looks sub-par. The Black-T finish is sexy. No idea how it will hold up compared to the ionbond black on the Specialist, but the ionbond can look a little dull. The TRP's black looks a little more "wet".
One thing that's been interesting is finding leather to fit the Specialist. The "Clark style" rib along the top of the slide kind of messes with the fit in holsters cut for other railed 1911's. I have TT Gunleather building one for me that I am hoping fits better.
