I've been using Leupold optics, rifle scopes, binoculars, spotting scopes, and range finders for decades. In my opinion, for $500 I don't think you'll find a better piece of glass. And their high end optics will definitely compare with anything else out there also. I have and use Leupold optics that are more than 35 yrs. old, and although they lack the advancements in coating technology and other advancements in today's optics, one still knows that they are looking through a quality piece of glass.
And when it concerns customer service, Leupold has set the standard, and lead the industry in this respect. Even when something was entirely my fault, such as dropping them, even running them over with my truck, Leupold has never blinked an eye and always fixed or replaced them at no cost to me.
And over the last couple years I have given Vortex a test drive. They too offer some great glass, and although it's difficult for me to say this, they are giving Leupold a run for their money in the optic industry. I have experienced their customer service as well, and like Leupold, they have yet to blink an eye in taking care of me, also without charging me a dime. At present I am using no less than 10 different Vortex optics, spotting scopes, binoculars, and rifle scopes.
I am extremely hard on my optics, so it's safe to say that if a weakness or flaw exists with either of the above manufacturer's product line, I will discover it fairly quickly. You'll get your money worth with either, IMHO.
