I voted other.
My Commander sized choices would be the Colt Commander (blued model 04691) followed by a S&W scandium framed Commander sized pistol, either PD or Gunsite.
I'm sure the CBOB is a nice pistol. There seems to be a lot of fans out there, but I like the "bobbed" frame about as much as I like finger grooved grips on a 1911, not very much.
On the XSE Colt, I don't have a need for the ambi thumb safety (I'm a righty) and I don't care for the "duckbill" grip safety. The standard Colt Commander (04691) has the nice "teardrop" single side thumb safety and my favorite grip safety (both like my 1990 Combat Elite).
I like the Commander size as a 4.25" barrel with a bushing which eliminates the Kimber and Springfield.
The S&W's are 4.25" barreled and have a bushing. Both are lightweight models which would be nice. The Gunsite has the short GI guide rod which I prefer, while the PD has the full length rod, but that can be easily changed out. I'm not too concerned about the external extractor since S&W seems to have done a good job with it. I'm also not too concerned with S&W's firing pin safety since the design seems to be more robust than the Colt Series 80 design (though different) and I've not had any problem with that system.
