I have a hard time believing that guys who spend the kind of time and money that it takes to be competitive in PRS, would choose an optic solely because it saved them a couple grand. That poll was specifically geared toward the top 100 finishers of the entire PRS series. The guys who win matches.....
What kind of money do you think sponsorship entails? There might be 5 people in the realm of shooting sports who actually get paid for what they do.
Leupold, Nightforce, etc all make great optics. Nightforce doesn't have a budget lineup for us to compare to the budget offerings from Vortex. Leupold does and I would say that the Leupold MarkAR line of optics is probably a superior choice to offerings like the Vortex Strike Eagle.
It's really all just hearsay and personal experience unless we have some real data about the number of optics sold vs. those that go back for warranty.
I have an expensive scope riding in a USPS box right now on the way back to be repaired by the factory.
My only experience with Vortex Warranty was on a $30 accessory, and they sent me a prepaid shipping label to return the broken throw lever along with the new throw lever (that I smashed off the scope dropping the rifle into a dump barrel) that they sent me, no questions asked.
Plenty of great options out there, it is a great time to be shopping for high quality optics.
