Having handled all of them, I would go with the MRC X2 or the Patriot, unless you really need a light rifle. In that case, the Kimber would be my choice out of those listed.
FWIW, I bought a Winchester EW and a Weatherby Back Country about a week apart, and it didn't take long to send the EW down the road. Everyone I know that has one is either upgrading to a better stock or planning to do so.
