Yes, I have Peter Bridgwood's presets loaded into Lightroom, and they provide a useful starting point.
I find Lightroom will do 80% of my raw processing well enough, and I use both 2012 and 2010 process versions depending on the image. But where I want better detail, highlight recovery or better colour in areas with rgb values above roughly 245 I still go to PhotoNinja. That applies to my Canon files as well.
