In favor of what? Debian-based? I admin a ton of RHEL servers, I they give me little trouble.
However, I haven't met a flavor of Linux package management that matches the elegance of FreeBSD's ports system. (Yes, I even find portage bothersome in comparison.)
Arch's Pacman system is a beautiful thing if you haven't yet had the pleasure. And if it's not in the official repo or is outdated, the AUR probably has it.
