You can continue to use Lightroom. Nothing wrong.
PDCU is useful for those of us (incl. myself) who do not have a prior software. PDCU is not bad but still has a few bugs. It does not bother me, but I cna easily understand others prefer other softwares.
If you like Ligthroom, keep using it.
My only suggestion could be to consider some specialised plug-in's, for example for lens distortion correction and noise reduction.
* For example, PTLens is excellent for lens distortion and more accurate than PDCU or other general softwares. This is particularly relevant if you use zoom lenses and need some accuracy in the lens distortion correction.
* For noise reduction, some dedicated softwares like Noiseware and NosieNinja (for example) give better results than PDCU or basic softwares. This is important if you shoot in low light conditions.
Hope that the comment will help...
