My opinion on a couple items...
One, Leupold has been around for more years than I care to count and they are (for the most part assembled right here in this country, especially their higher end optics.
Vortex isn't. The lower end optics are Chinese the higher end oprics are Phillipene in orign. That might not be all bad, depending on your patriotic views.
Two, when you return a Leupold for service or custom shop work, it's done in Stevensville, in their shop, same with warranty work.
Vortex has no shop to speak of. Vortex Optics is a distributor so when you return a scope, it's replaced with another, which should tell you the inherent mark up/profit margin on scopes in general. Their 'custom shop' work is done by contractors, not them.
Both have basically identical warranties, but keep in mind that the 'Lifetime transferrable warranty' is customer driven, not maker driven. Customers demanded an iron clad warranty and manufacturers/distributors delivered. Not that they wanted to. They had to because Leupold initiated that policy and everyone had to follow. If they didn't, at least on moderate to high priced optics, they would have been 'out of business'.....
The cost of that warranty, whether it's a repair (in the case of a Leupold) or a replacement (in the case of a Vortex, is built into the initial purchase price which is the main reason optics are so expensive.
Things to ponder. I have both, Leupold and Vortex as well as NightForce and US Optics and at least in my view, any optic is only as good as the eyeball thats looking in the ocular and no better.
You get what you pay for b ut always keep in mind, when you groan about the price that, that price encompasses returns. In essence, you pay for the chance that you scope might have to go back, whether it does or not.
