If they both fit you well, I would reccomend the Kimber. That's just from my personal experience with my Kimber. Plus, it's a .45.
If you havent shot them, I would try to though, just to see which one feels better to you. Which one I would pick dont matter a lick when you are the one shooting it. See if you like one better than the other. Either way, jump on one of them with both feet. You never know when the next chance you might have at one will be.
