I have a 6-18x40 buckmaster, a 6.5-20x40 EFR Luepold, and a 6-24x40 4200 bushnell. They are all very comparable with view and brightness. The Luepy wins for feel of quality, and I expect durability.
The buckmaster is very nice to use, but if you are shooting short range 25 yards, make sure you can focus down to those ranges, as the model I have starts at 50 yards (it can focus down to 25, but just)
