Lately I've been captivated by the BW - especially when the blacks are really black. That may sound like a given - but sometimes blacks aren't black. I like what I see when I convert a Nikon file - there seems to be no in between.
Now -- when i push this file to the printer - that may be a different story. Depending up the paper I may get a bit of some purple tones - just a touch. I'm still working that out.
