I know three people with Kimbers and they have had good luck and are very satisfied with them, no problems, go bang every time.
I've only had a chance to shoot one Springfield and that was years ago, a plain jane, GI type and had no problems with it during several sessions.
To me, the answer to your question is a coin toss. Both should be good and serve you well, pick the one that seems to be the best in your eyes.
