I see you are shopping as well...........
I have numerous brands mounted on numerous rifles, Leupold, Zeiss, Nikon, Vortex and even a Bushnell but I like the Vortex Viper line the best for value versus ease of operation and clarity. They aren't Nightforce or S&B, but they do a good job for the money spent.
Candidly, the all appear about the same to me when I look through them, even the Bushnell (Japanese LOE) is good.
Good points and bad points... Thne Leupolds operate smoothly but are getting pricey. Ziess also works smoothly but the offerings are limited. Nikon's have a bulky magnification adjustment (I have a Nikon on my ML because it's in realtree and matches my CVA). Vortex work slick but they are heavy scopes and the lone Bushnell is on my 44 Magnum. It's a Japanese Bushnell Deerrslayer that I don't believe is sold anymore. Nice scope, unlimited eye relief and fixed parallelax but it's a handgun scope and it's only a 1-4.
