There is no software that knows the Canon color profile as DPP does. Aperture, LR, Phase One etc. might have some nice features but the color tone would never be as good and clean as DPP.
Well, it's true that DPP recognizes and applies the Canon Picture Style chosen in-camera, and also ALO. But I don't think that means the color is especially 'good and clean,' it just means that Canon's programmers have accurately guessed what you find pleasing in an image (which for some is oversaturated color, at least with the Standard picture style). When I compare picture styles with a color target (X-rite ColorChecker Passport), you can see clear differences. It's possible to set up a preset to mimic Canon Picture Styles in another RAW processor, if you like. Other processors handle image noise much better than DPP.
I like to get my colors and exposure accurate on the camera as I'm photographing so I do use the picture style, kelvin, ALO and HTP to fine tune as much as I can on the spot. When I bring my files to other softwares, non of the settings gets recognized and I get to stare at underexposed photographs with awful colors on my monitor. Even with HTP and ALO off the colors and exposure still shifts. From my testings DPP works best but I'm aware that it still needs improvements. I'm curious about your raw workflow and would love to see some images.
