Well I'll jump in on this one. I know a lot of people like LR and I took lessons on it and downloaded the trial version. If I was a pro and had to do mass editing I would use it. NR is better and it has so many more options. Not that I have not come up with procedures for mass editing using DPP.
I just find also that DPP edges out LR when it comes to crisp images. Also personally for what I do I think PS is far better at sharpening than LR. I like to do birding and I like the eyes and beaks to be as crisp as possible. I have this sample.
Here is the the DPP crop. Look at the jewelry around her neck
Here is LR.
No matter what I tried I could not get it to look as crisp using LR. I had multiple strips torn off me at DD Review stating I did not know what I was doing, blah, blah, blah. I was also told not to pixel peep as no one looks at that level. That is true but I often crop my bird shots, sometimes quite a bit and I need everything I can squeeze out if it.
Maybe I don't and have not made enough effort do so but I did offer the RAW file and challenged anyone to match it and tell me what they did. Only one person posted an image and it did not look much better. I tried and I don't give up too easy. I'll take something on and spend weeks or months to figure it out.
