Not long ago I owned a variety of scope brands including Leupold, Zeiss, Trijicon, Bushnell, Nikon, and Vortex. All of those have been replaced with a Leupold with the exception being the Bushnell Elite 6500 2.5-16. I would own another Trijicon, and I wouldn't pass a good deal on another Elite 6500, but as for the others, Leupold gets the nod pretty easily. My favorite of the Leupolds I own is th VX-3 LR 4.5-14 with a 30mm tube and side focus. I have 2 of those, one in 40mm and one in 50mm, and they're great.
