The TIFF files seems remarkably crisp and sharp - almost as if the files were already finished and need little or no further adjustment.
Here is a simplified explanation: DPP automatically pays attention to the cameras settings for color space, bit depth, and "camera styles" that are used to produce in camera raw to JPEG conversions. Because Canon, Nikon, Sony, etc., choose to place those settings in a "black box" (technically: an undocumented data fork) in the raw file metadata, Adobe would have to crack that black box (and it is different for each camera model) open to apply them as a default for each raw file.
As with all good raw file processors in DPP you can tune those settings and do even more more. If you are doing it "right" whichever raw processor you choose to use should be used for doing the heavy lifting of processing your photos and for most photos post-processing in Photoshop should be pretty minor.
