The newer VX scopes have better lens coatings than the older Vari-X line-up, and the VX-II 3-9x is now equivalent to the older Vari-X III 3-9x. The new VX-II 3-9 is a very good scope. I have one of the new ones and an older Vari-X II 3-9. The VX is a better scope. The new VX has click adjustments where as the older one had friction adjustments.
You can get the latest Leupold catalog and read about it, or the Leupold web site may have some info on the changes that took place when they went from the Vari-X line to the VX line.
