Just a counter point: I love yum. It is, by far, my favorite package management option. Managing yum repos is a breeze vs every other option (the toolchain is one command, vs a half dozen commands and hours of manual labor to setup a new repo for Debian/Ubuntu). I also prefer it from the end user perspective.
apt-get is fine, and I wouldn't be at all unhappy with servers running Debian, but yum is my preference.
