Actually I find highlight and shadow controls better than DPP. As for sharpening. Have you used the export pages output sharpening?
I'm getting into Lightroom a bit more, I can see it's more powerful, whether or not I need all of those options is another question. The noise reduction available in LR is a nice feature. I'll retract the statement about DPP sharpening being better, but I do think it's pretty good. If there is a downside, it's that you don't see it in the raw photo until doing the conversion to JPEG.
