With all things being equal, either of them will do what you want.
However, all things are not equal. you will have to deploy kix to all of your clients (not hard, just one exe.. bext practice)
WSH is a bit harder to use/code and doesn't have the functionality that kix does... for the equivalent functionality, you would VBS... which is that much harder to code (but not much)
then you have support issues... you aren't going to get it for free for either product, except for boards like this one... and I'm not aware of any vbs boards, but there are undoubtedly some out there.
Your network, your call...
