The main difference is about policy. A dist-upgrade done with apt-get,
aptitude, synaptic will always upgrade the package based on your
current installed set and thats it (it has no policy beyond the
package relationships). In contrast, the dist-upgrader will ensure
that one of {ubuntu,kubuntu,edubuntu,xubuntu}-desktop is installed
(and if not guess which one you need based on your installed packages)
and will do things automatically that are usually described in the

Consider the dist-upgrader a high-level policy enforcement
application. There is nothing wrong with a normal dist-upgrade, it is
just hard to express some things with package releationships.
