3dfx's FSAA is still the best overall, but it doesnt tend to make the text slightly blurry.
If you want to avoid blurred text completely then your probably better off with ATi's SmoothVision in it's Quality modes.... not quite as good as 3dfx's implementation but reasonably close and the text shouldnt be as blurry.
Do NOT use SmoothVision in it's 'Performance' mode as that uses an entirely different AA algorithm.
The classic SuperSampled AA used on the original Radeon, and GF1/2 looks acceptable, but is distinctly inferior to either SmoothVision or 3dfx's implementation.
Avoid nVidia's Quincunx as it applies a blur filter on top of the scene being rendered and can make the scene quite blurry, though it's excellent on jaggies.
Anisotropic tends to off-set that somewhat, but anisotropic filtering won't really impact text... so that will still be blurry.
nVidia's multi-sampled AA looks respectable, but still tends to be a bit more blurry then even classic SuperSampling... though it has the rather significant benefits of superior performance and it significantly reduced the memory usage of FSAA.
My knowledge of Accuview is limited at this point in time, but from a purely visual impression it looks markedly similar to nVidia's typical MSAA in modern games.
Overall, if FSAA is the only deciding factor I'd go with 3dfx, though if text crispness is a huge factor then ATi's SmoothVision would be a better option.
