I like the Colt. I don't like the Kimber (personal preference...other folks love 'em, and that's OK, too). There really isn't anything wrong with any of your choices. Sir, you are suffering from "paralysis by analysis." Just get one.
Regarding the 1911: "The gun was designed to function. If it's built to the proper specs...it'll run. It's a machine. It doesn't have a choice." 1911Tuner
