I can see the value in a range of choices. As long as they are purposeful choices, clearly identifiable.. With a consistent desktop developed so that users can find what they want, arrange it in the way that they want and use it in the way that they want without needing any technical skills beyond their normal day job.
Something along the lines of;
Linux [name] for general/SOHO use and the one that most users would run .
Linux [office] for corporate professional work use.
Linux [technical] for engineering/development use.
Maybe one or two others.-
