I respectfully disagree with that. In my opinion the point of the different *buntus is convenience for beginners rather than solving hard problems. To that end I have taken Ubuntu machines at work and installed KDE and the whole process took no more than a few minutes and was pretty painless. But that's not necessarily something that a Linux n00b might realise they could do (nor even want to try)
If you look at any of the more "hands on" distros then you might find a couple of themed variations, but generally users will just recommend you install the base distro and change your personalisations yourself. As an aside I went through a phase of running a different DE/WM each week on ArchLinux. Never had any issues there.
