I compared the Burris 3x9x40 with the Nikon 3x9x40 and ended up with the Nikon on my Sako .338 Win Mag. It seemed brighter, had better optical definition, and the eye relief suited me better.
The adjustments are repeatable and so far it has withstood the recoil very well.
I wouldn't hesitate to buy another.
Hope that helps.
