I was wondering why fedora has choosen yum over apt-get

[Kristof Vansant]

What are the key benefits of yum over apt-get cause I got a friend telling
me yum is crap and I should switch to apt-get in stead.
Apt-get goes really fast in comparisment to yum.
But I tell him there must be a good reason why fedora uses yum, I only don't
know what :).

Can someone explain it to me.

Thx,
