For most raw files, I find LR3 does an exceptional job and I can easily exceed the quality I would get from DPP. However; there are times that no matter what I do in LR, I just can't produce a jpeg that matches the quality of DPP, it doesn't happen often, but it does happen. I also prefer the colors I get from DPP as compared to LR3, but my colorchecker passport seems to have solved that problem. I think Canon might be holding back just a little secret sauce in their raw file format but I can't prove it....







where it sharpens the picture when you're viewing it at the size that you're viewing it at. However, when you export it it sharpens it at the pixel level, which results in a lot less sharpening. In other words the picture in dpp is oversharped (or nicely sharpened, depending on the picture) but the same picture viewed outside dpp is less sharpened.
