DPP is a very competent program, but doesn't have the feature set of ACR. And ACR works best when you make custom camera profiles. I suggest you take a couple favorite images and make them look as good as you can in each program, then evaluate the resulting TIFF file. Look for sharpening artifacts, smoothness of tone in skin & sky, etc.
If you really like DPP, then to take it farther and really make it an excellent tool, you'll probably want to use Canon's Picture Style Editor
to make custom recipes to suit your taste. I find "Standard" too harsh, but like its color rendering. I like the contrast of "Faithful" but find the colors too dull, so I made my own Picture Styles to suit various subject matter.
Either way you go, you'll get satisfactory results.
