That's a tough list, I guess it really boils down to if you want railed or non-railed. You mention the TRP and the Loaded Operator, what about the TRP Operator? Be forewarned that if you shoot IDPA, the TRP Operator is not IDPA legal due to the 5" bushing-less bbl.
Looking at the options, the Kimber would be on the bottom of my list.
Regarding the Double Star...too new in my book.
If I were looking for a gun to be more of a carry piece I would go for the CBOB, I really wish DW would make the CBOB with the finish from the valor. The Valor is hard to pass up, but if you all ready have some non-railed Gov't sized 1911s, I'd opt for the CBOB.
So again, railed or non railed?
Non railed 5" I'd go with the Valor unless you can't find one, in which case the TRP would be my second choice.
If you don't want a rail, but also don't want a gun that's almost identical to your Sig (pending on exact model), go with the CBOB.
If you want a rail, I'd go with the Loded Operator if the TRP Operator is not an option.
