The most striking advantage is that yum is smaller than apt and thus
easier to maintain and code review. That and the fact that it didn't
have the political stamp of Debian on it was the reason RH chose to
add it to Fedora (but note that up2date supports apt repos, too!)

Here is yum author's reasoning (http://linux.duke.edu/projects/yum/question=
 Q. Why not just use apt-rpm?
 A. a number of reasons:

   1. I didn't wanna
   2. At the time yum started apt didn't do a number of things I
      needed and it didn't do a number of other things very nicely
   3. I wanted to learn python
   4. yum is relatively pretty and relatively nice and has
      significantly less legacy baggage than apt
   5. Size of codebase in apt (find -name \*.cc | xargs wc -l): 40141
      Size of codebase in yum (find -name \*.py | xargs wc -l): 4681
   6. Yum is written in python and therefore can benefit from code
      theft from anaconda and up2date - I did indeed steal the lilo
      updating code directly from up2date and learned A LOT from

The list looked different and caused grief at the apt lists
