One thing to consider also that might make a difference to you depending on how far you plan to shoot, is the Burris has A/O, and this particular model Leupold doesn't. For the type of varmint shooting I do at the distances I shoot, I personally wouldn't have a varmint scope without A/O, or preferably side focus.
As for the price difference, it depends on which scope you like better. Only you can determine if the price difference is worth it. Leupolds are just expensive compared to their competition, and the price difference isn't necessarily because they're better. Often, they're no better than other scopes costing way less, in some cases actually inferior. One thing Leupold does offer, though, is plenty of options, which I think contributes some to their higher price. For fairly short range, low light predator hunting, it wouldn't be worth the price difference to me. Now, if that was the side focus model VX-III at that price, it would definitely be worth it to me, as I prefer side focus to A/O. For super precision long range shooting at small varmints like prairie rats, I personally like the VH reticle enough that I'd be willing to pay a little extra to get it.
