I met with the same quandry just about 3 weeks ago.
In short, I went with the Springfield for several reasons.
1. Comes out of the box with everything that I already would have done to a 1911.
2. Price was perfect, $575 out the door for the loaded full size, in blue with a msrp of $670.
3. Trigger felt better to me than the comparable Kimber at 2 of the 3 dealers that I shopped.
4. I wouldn't feel bad about replacing/trying different "modular" parts in a SA.
The Kimbers are nice, fit and finish is definately first rate, but there seems to be more and more compromises overall with the latest quality control with the Kimbers. Not a judgement, just an observation based on the guns being shot in my club and the experience of the 1911 guys "In the know" that I hang out with.
My SA was fully loosened up by the third box of ammo, and shoots great groups at 25 yards. In fact, it makes me look great on the range!
If you want a gun that you really can play with and customize based on what you want/like, then the SA is the perfect platform, while the Kimber is a little pricey. If you want a great gun out of the box that you think you might never do anything other than a trigger job to, then go with the Kimber.
BTW, my SA has a 3/32" total trigger travel, with a 4lb trigger out of the box!!
If you go with the SA, just tighten the guide rod sensibly, and it won't rattle loose, and trade in your 16lb recoil spring for an 18lb one right off!
Have fun, and either gun would be great. I'll probably end up with the Kimber myself, not to long from now, just to round out the selection. Now, if I can just convince my girlfriend..............
