In my opinion and experience, the Leupold VXII is a better scope than the Fulfield II. Is the VXII worth the extra money - again, in my opinion - yes. Please keep in mind that I am not a true Leupold fan (even though I own a few Leupold Vari-X III scopes).
If you really want a great scope, especially for the money, look at the Bushnell Elite 3200. It's less than the VXII and a better scope with better optics.
