You're not comparing apples to apples...you're comparing apples to steak.
The grip of the XD is harder to conceal than the Kimber. The trigger on the XD is horrible compared to any 1911. The accuracy of the Kimber is incredible for such a tiny gun. The Kimber may require a break in period of 300-500 rounds. Mine have all ran perfect out of the box, but Kimber does recommend the break in period. As you pointed out, the XD does have a larger mag capacity.
In any case, I would rather have the steak, so I would go with the Kimber.
