There are a couple of conclusions to make. First, Anisotropic Filtering can be a tremendous benefit in image quality without much, if any, hit in performance. Second, the leading chip manufacturers (ATI and Nvidia) have, as might be expected, different approaches for accomplishing AF. Third, no one thing, AF or AA is going to satisfy all applications or users needs. Rather a combination of AF and AA will produce the most satisfying results, and fourth, you're on your own in a world of trial and error to get THE best results trading performance for image quality on a game by game basis.
However, if you're lazy like most of us you can set your ATI system for 2x AA and 16X AF and set your Nvidia system for Quincunx AA and get overall good results. And yes, one system will beat the other in some benchmark, but you don't use your system for just benchmarking do you?
