Been using Burris scopes for years on eastern white tail deer, mule deer, pronghorn and elk. I have never been disappointed by a Burris and they have a forever guarantee.
That said, for varmint hunting, where I do not travel far and the recoil is way down from a deer rifle, I have never, until this week spent a lot of money on a scope. I have a Tikka M595 Sporter in .223Rem. Topped with a Taiwan made Tasco 6-24x40, the rig will shoot honest ragged one hole groups consistantly at 100yds. This week, I bought a Burris Signature 6-24x44 and put it on a Savage 12FV in 22-250. At the range, I cannot see any avantage to the Burris over the Taiwanese Tasco. The Burris cost six times what the Tasco cost. Through both, I can see the holes at 200 yards. Both are holding zero. I don't regret buying the Burris, it is a nice scope and very clear, but when not a lot is riding on your shooting, you may, many times get by with much less expensive optics. This Savage/Burris rig is my first rifle to have the optics be more costly then the rifle!
