I wish ACR is good as NX2 since I need to deal with multiple raw formats (Nikon, Sony, Olympus, Panasonic and sometimes Ricoh and Canon), but NX2 is still much better (quality wise) than ACR.
Noise control.. you can try to see if the new NR 2012 is better (if you shoot high iso, NR 2012 is not used by default but the older one is used instead)
Longitudinal CA correction.. I think this is not used by default but when you need it, it works great. I don't think there is such function in ACR.
CA/fringing.. NX2 can deal with them automatically, but I need to use brush to do the same in ACR (otherwise fringing removal can give odd results).
Distortion correction.. I think Nikon knew their lens...
ACR seems better for highlight recovery, and I kinda like ACR's gradual filter.
