I voted for Duff's. Their lunch special is great. There are far better wings available in the area though. Oh, and for the record, the always have honored my requests to have my wings not served swimming in sauce.
I found the Anchor's wings to be a decent size (much bigger than Duff's especially the flats) but they were very soggy and undercooked, even after having request extra-crispy. Also, I think their prices were WAY too high.
If you don't mind occasionaly lousy service (though not a fault of the staff, just the volume of business) I highly recommend The Pub, located on Broadway (near Transit) in Depew. They have some of the best wings I have ever had, and the quality is consistant. They have a great selection of styles and flavors ranging from mild to over-the-top-melt-your-face-hot, jerk style, baked italian pub style, and char-broil bbq on par with La Nova's.
Additionally they have Hi-Def projection screens mounted to the ceilings to provide a great game day experience.
I also recommend their steak fries...
