What was the AA used in inFamous SS? That was one of the best AA methods we've seen thus far from the PS4 and X1. Would love to see more games use something similar (especially since the more high end solutions seem to be a tad out of reach right now).

It is one of the best post-processing AA tech right now... Ryse uses a similar AA tech (Crysis 3 too)... it is called SMAA TX2 (Enhanced Subpixel Morphological Antialiasing).

You can find more here: http://www.iryoku.com/smaa/

But it is not the best than render-processing AA like MSAA or SSAA... there are better AA too like CSAA (a better version of MSAA) or QCSAA (GPU gone down with that one) or TXAA (better too  but hits the GPU).

I prefer SSAA in PC over MSAA but I think for console 1080p + 2xMSAA (or 4xMSAA) will give the best quality with the lowest performance hit.

TXAA has a problem: it tends to blur the image too much. The heavy blur in Ryse comes from that kind of blur with SMAA 1tx  (and not really from the upscaling).

SMAA 2tx is the best post processing AA out there without pure super sampling SSAA (it uses temporal super sampling only by "smartly cheating" using previous frames). Even DF said it reluctantly in the Infamous face-off. If you want better stuff you have to use at least the very expensive 4xSSAA or combine SMAA 2tx with 4xMSAA.

But using only 4xMSAA has problems: it doesn't deal with shader aliasing and it leaves some aliasing particularly on motion.

 

And 2xMSAA is more expensive than SMAA 2tx, do you think the AA used in Titanfall XB1 is better than SMAA 2tx? I don't think so. You can still see aliasing even with 4xMSAA. That's why even the games using only 4xMSAA (like many PC games or even the Order) must use other post process blurring solution to hide the problems not dealt with like the aliasing in motion and shader aliasing. 

The ideal in fact would be to combine MSAA + SMAA 2TX: it has already been done and is called SMAA 4x.
