It's nice to see Sabayon mentioned. I've been using it at work for a few years now. I'd used Gentoo for a long time at home previously, and wanted something at work that felt like it, but didn't have time for the tedious installation process, nor the long builds if I suddenly needed to pull in a large number of packages for other purposes. These are the very issues Sabayon purported to address with an out-of-the-box setup and a binary package manager. I tried it, liked it, and have used it since.
The package management tool (Entropy) is nice. It feels a lot like Portage, but also handles a few other tasks (configuration updates, mirror selection, etc.) within the tool itself. It's a nice compromise between Portage and the binary package managers you find in most popular systems.
