Bugs in NX2 include erratic results when printing and general stability issues - i.e. sometimes it just crashes. Sometimes it prints so that a part of the image (a rectangular block ...) is missing. I print through photoshop if this happens so it's not a big deal. The stability of the latest subversion is acceptable - if I work on a hundred images it may crash once or twice. I've never lost data because of it, nor has it ever made an "incorrect" conversion. There used to be a bug which turned off sharpening when you touched exposure compensation but that was fixed.
The LR2/ACR 4.5/4.6 camera profiles mimic the Nikon picture control basic looks - and this part works great - the tones & colors indeed are similar. But I find the image definition (noise, sharpness) to be better and more consistently "good-looking" with Nikon's conversions. Other people may have different opinions, but I always convert my NEFs in Capture NX2 now, and I then may use LR2 for organizing large numbers of images (not NEFs, but images converted using Capture NX2) and printing with slight tweaks as needed. I love the LR user interface and wish Adobe and Nikon would collaborate in incorporating Nikon's algorithms as an option to be run from the LR2 user interface.
