GeForce 7950GT
Radeon X1950 Pro
GeForce 8800GTS
Although the shots don't quite line up with each other, they're still within the same ball park. The easiest spot to see aliasing between 4x AA 16x AF shots is on the center of the image - the 'nudge' on the upper part of the station (above the interceptor on the GeForce 8800 shot). With motion, the aliasing is very noticeable on the Radeon X1950 Pro, but less noticeable (though it can still be seen clearly on the GeForce 7950GT and GeForce 8800).
With 8x anti aliasing, we see very little difference between 8xS, 8x CSAA, 8xQ, 16x CSAA and 16xQ. 4x AA seem to be enough in this scene. The GeForce cards does a much better job minimizing aliasing in this shot than the Radeon X1950 Pro. However, in our aliasing in motion test, the GeForce 7950GT falls flat against the Radeon X1950 Pro and GeForce 8800. You can see it if you look at the slideshow below.

8xS on the GeForce 7950GT does a lot better job than the card's 4x MSAA, but there's still some aliasing near the end. Its just about as effective as traditional 4x MSAA on the GeForce 8800. With 8x CSAA and 8xQ, the GeForce 8800 was able to take it up a notch, reducing that little bit of aliasing near the end, with 16xQ offering the best results - at par with 4x MSAA on the Radeon X1950 Pro. So, it would seem the card that's more effective in dealing with aliasing here is the GeForce 8800. It may still exhibit some aliasing at 4x MSAA, but it does well on both scenes while the Radeon X1950 Pro exhibits more noticeable aliasing on the on the first test.
