I have them both. DPP is much faster, but lightroom is superior with editing. I feel DPP does a much better job with the eye dropper for white balance. It also does a better job than lightroom with sharpening. With DPP I can usually get a feel for what the picture will look like on the screen and be done. With lightroom I usually end up going back a second time because I don't like the first export....not sure why.........but just the facts.

sorry about that
