Love my VX6, was a great deal used. If weight is a factor, and nothing rivals the weight and features of the 3-18x44. Unfortunately they are creeping into nightforce SHV price range, which is a sturdier, better scope if you don't mind 10 or more extra ounces.
Also consider Leupold is launching the vx6HD models, the 3-18x44 was discounted to $749US at cabelas in the states on Black Friday. I expect current models to be cleared out for the new ones.
