My personal preference is the grip of the SK, but grips are a personal thing so you may find the KH more to your liking.
Even with that said, you will find varying grips from year to year among the same model. The KH of 67-69 had a much higher grip that the later ones. I found the SK grips very similar from year to year and find that they are somewhat smaller/narrower than the KH.
Still, your best move is to try'em even though I expect you will find good things to like about both.
