Another benefit of Gentoo is the wealth of knowledge you'll find at http://gentoo-wiki.com and http://forums.gentoo.org . Additionally, the portage system makes everything rather easy to do, once you get the hang of how it all works. Is a certain version of a library causing a problem in a program? Just mask that specific version and run a single command to re-install to a different version of the library and update all programs that depend on it.

I started with FreeBSD and switched to Linux when I couldn't get proper drivers. I didn't like Ubuntu or Debian, but I've been quite happy with Gentoo, and I'm getting ready to put it on my third computer.
