Perphaps you are referring to the initial, default rendering provided by Lightroom?
Like Mort, I find that my P45+ LR conversions are excellent. But Lightroom's initial 'guess' at how the file should be rendered is often poorly color balanced. C1's initial rendering is spot on. I shoot nature, so my lighting is always different. If you are in the studio, you can set LR to the proper balance for your strobes.
It takes an extra step or two to bring the LR conversion in line, but I also find it rivals C1's quality (as of LR v1.3, not so for previous versions).
Hope that helps,
Brad
