I'm not surprised about the Burris being brighter than the Leupold VX-II, but I am surprised that it is brighter than the Elite 3200.
That notwithstanding, I have heard quite a few people complaining about certain "particles" developing over time within the Burris tube. I own 2 Black Diamonds, and I haven't had any problems with them yet, but I am a little concerned. On the other hand, no one has ever complained about "debris" on their Leupold scopes.
