I cant verify the others, but the burris is quite durable. Ive shot hundreds of 3.5 inch shells out of my sbe2 with the burris on with no issues at all. The burris is a good sight but I still recommend the Vortex for the ability to have more intensity settings. It may seem a small issue, but having only three settings like on the buris does not cover different lighting situations that occur while hunting and so I think the Vortex may be a better option. Vortex is well known for their customer service, so if I were to do it again I would look at the vortex.
