The Debian exiles will miss apt badly. Apt was what made me move from Red Hat.

Having used Zypper, Yum, Apt, and Pacman, I'd have to rank them pacman > zypper > apt > yum. Have you tried the others? Apt syntax is so cumbersome using either the Suse or Arch package manager.

Gentoo's emerge/portage is pretty nice, though it's been years since I've used it.
