I too considered a ZX-14 before I bought my new C14 a few weeks ago.
As many have already noted, the factors that swayed me were: comfort, insurance, and storage. If money was no object, I would have both, but I knew that the novelty of having such a powerful bike would wear off after awhile, I would rarely use its speed capability, but I'd still be saddled with the high insurance payment.
I will probably only do minimal touring on my C14, but I really like the convenience of the hard bags. I will ride much more since I can easily bring my gym clothes, lunch, protective gear, and other things to work. I think my Z1000 will be relegated to the days when I KNOW I really don't need to carry anything.
