Here is a nice links page that is pro-Debian (which I am), Maybe someone knows of a pro-Redhat links page and will post it. I have no major beef with RH, it's just not my cup-o-tea
. I think it really boils down to your own philosophy. If this is your first journey into Linux (as I have no idea of your experience) you might also want to consider Ubuntu (that is, if you're actually looking for a distro to use, and not doing some paper or something on the differences.. again, no idea). It is coming along VERY nicely, it's based on Debian using Gnome (though obviously you can install any other wm or desktop environment). To me, it seems that Ubuntu is the "desktop" version of Debian, easy to get into, current packages and stable. This does NOT mean it's a "light" version, by any means, it's just a bit more polished. I'm keeping a close eye on that distro myself, it's gaining recognition very rapidly (and for good reason, not just cause it's the new, elite thing to do hehe).

BTW, are you talking about Red Hat or Red Flag, because you mention both?
