Good thread, I didn't remember all the details anymore (and I'm not sure I ever had enough information on temporal AA anyway).
Anyway, I'm OK with FXAA. As far as I've seen, it doesn't really make the image too blurry but it does eliminate the jaggies well enough. Of course I prefer better methods if I have the processing power, but I'd much rather use the extra power for more noticeable things than better AA. Whenever given the exact choice, I rarely go above 2xAA because it seems to be the biggest help and I don't care about further improvements enough to bother playing with the settings to see if I can go higher. Of course with older games, the choice is easy: I can go higher, period.
