I missed this earlier. Here's the reply I sent privately for those that are interested:
Ahhh Gentoo.... :)
RedHat is said to be the Windows95 of Linux's because of it's easy to use interface. It kind of glosses over the details while giving you a fully functional, yet powerful Linux PC. It's great for those learning Linux and for those that need a server up lickety split.
Gentoo on the other hand is quite detailed. Everything is compiled from source. This makes it take forever to install things (like a few hours, or up to a day to install OpenOffice.org

), but you end up with a program that is completely optimized for your system. The entire OS, userland tools, and programs are build with optimized compiler USE flags. This lets you compile a program with code that ONLY works on athlon XP or a Pentium Pro or dual PII machine. Same with dependancies. From a desktop users perspective you can edit a flag or two in a config file, and NEVER have gnome support (for example) if you want a KDE only system. Gentoo also has a cool rsync based package management system called "portage". If you're used to FreeBSD it'll seem like a funky version of the ports tree.
Gentoo will take quite a while to install. It's extremely nitty-gritty, but you can end up with a very powerful system. The documentation on their site is top notch, and they have one of the friendliest and most helpful forum communities I've ever seen. I've not tried it on a server yet, only the desktop, and I absolutely love it. There was once a time when we installed Gentoo on ServerMatrix boxes, but with the number of orders we receive now we don't have the time to watch over every installation like that.
