Although I use CS6, it shares the same ACR as LR. Starting with CS5 and now especially CS6 the noise control and sharpening are far superior to what I could get out of NX2. ISO 3200 from my D300 was barely useable with NX2. Now it's like I have a new camera.
Granted the colors from NX2 are WYSIWIG, but shadow recovery is far superior in today's ACR. With NX2 I always found I ended up with a lot of blocking in the blacks.
Also today's ACR doesn't have U point technology, but you can still do local edits.
The interface is much more limited in NX2 as well. You can't push exposure more than 2 stops and there are limitations in other tools I find too restrictive.
When I used NX2 I still did my final processing in PS. As Alan mentioned, you can keep the free View NX2 to show where your focus points are. With landscapes at f20, that's not too critical.
I also keep View NX2 on my laptop just to verify my transferred images when I'm on the road.
