I think, when you grow up outside of upstate/western NY you don't really know what a real Buffalo wing is until you go there and have one. And even then, you're likely not to fully grasp the buffalo wing.
Much like NYC metro area is saturated with any number of great Pizza places making that area arguably the best region for Pizza (not deep dish...don't worry Chicago, you're still good), Western/Central NY is the best region for wings and host numerous places to get a great wing (or dozen). The people who live in that region can tell you about the subtle differences from one wing joint compared to the one down the street. Most outsiders cannot tell the difference and hence do not have the distiguishing palate to tell the difference from one wing joint from another or a really great wing from a decent wing. And, that's ok.
It is possible there are good places to get wings outside of that area, much like there are great places to get pizza outside of NYC. But pound for pound (and wing for wing) upstate/western NY has the best wings at a long list of places. The Anchor Bar may be the original, but there are dozens and dozens of places to get great wings in many of the small towns and larger cities that dot the highways and byways of the Region. Any one who only names that one establishment in the region in a list of "best" wings, has not likely been to any other wing joint in Western, NY.
I can tell you of a great place for wings in Greensboro, or DC/NoVa/MD, or Greenville, NC or Virginia Beach, or Pittsburgh and the like, but it's not like home. None of them. They're good, and I eat wings outside of Western, NY, but its just not the same.
And I won't argue about who has the "best" wings. That's very subjective and slanted on where you are from and what your taste buds are conditioned to enjoy. But "authentic" is very argueable and you have to go to Western, NY. I wouldn't tell you the choicest steakhouse is in Buffalo any more than tell you that the choicest seafood is in Oklahoma. So, I won't agree with anyone who says the "best" buffalo wings are in NOT in Western, NY.
I mean, really...would you believe me if I said the best Philly cheese steak is in Columbus, OH?
