Ive been trying to sort out which way I wanted to invest my time learning software. I own CS4 and CNX2 and I've also played around with Lightroom 3 while it was still a beta.
I went out and shot some of the fall foliage a few weeks back and wanted to sort out those that are wall worthy. I fould one lovely shot of some golden leaves in a nice bath of sunlight and shade. I put this picture, side by side, in CNX2 and ACR 5.7. After careful line up of a small section of this photo I was able to switch back and forth with out any shifting of the picture.
Although at a casual glance it wouldn't appear that there was much difference when you paid attention to one spot the difference in clarity was huge. I have it running, rock solid, on a i7 920 machine that I built a while back. Maybe new isn't better?

If you are evaluating software, probably comparing images with products you are still learning is the worst way to make a decision. In a side by side comparison with people who are expert in any of these products, you woudl be hard pressed to pick a winner. The real difference is in the way software can be used rather than the way you can use it at the beginning.
I use Capture NX2. It has several strengths. One is the ability to accurately process Nikon NEF's with the actual camerea settings - and change those settings in post processing. Another is the ability to selectively apply edits. A third is its simplicity - a quick edit can be very powerful. A fourth is the file efficiency - you work with the NEF image and maintain lists of edit steps rather than multiple copies of an image (changes are non-destructive). Nik is a software company and their work makes the product very powerful.
It's disadvantages are not a big deal to me. It can be a little slow working with batches or multiple images. It does not do cloning as well as CS5, but is still good for basic things like dust spots, removing powerlines or twigs, etc. When resizing it does not provide the ending file size until after you apply the changes. NX2 does not use all plug-ins - most are designed for Adobe products. NX2 cannot create watermarks. Nikon is not a software company, but their required changes and functionality can limit Nik and lead to "issues".
