I was using CS until CS3 came out, and was pretty happy with my conversions (used LAB method, with additional adjustment layers). Now with CS3, I find I really like the new black & white conversion adjustment options, but I also really like the conversion option in ACR. Both options are also faster than my process in CS.
I checked out the Russel Brown show and he has a script to incorporate the two, and on a number of photos at the same time, and that is really interesting. However, it avoids the options to convert directly in ACR. I do like the ability in the black & whtie adjustment to drag individual colours directly on the image, but I could probably still do that if I converted in ACR, then fine tunes with bnw. You can also save the settings in ACR for use with future conversions, like creating an action in PS.
I was wondering if anyone had a preference for one over the other, and why.
