Different manufacturers "interpret" colors differently when the file is processed. You will see this in the JPG files. Even the standard Adobe Color profile will be a little different from camera to camera. Which one is better is not a question with an answer. It is subjective. Depends on you subjects, the light, your tastes, etc... Lenses can also adjust this a bit so it's not concrete.
However, if you use a color chart and make a profile from the raw files, this can be neutralized. You can get pretty much exactly the same color across different cameras this way. I would do this when shooting two different brands on a shoot. Xrite colorchecker profiles would align colors.
If you shoot JPG though, then each camera has it's own "profiles."
