I use a linux distribution called Gentoo (
http://gentoo.org).
What I like about it is how easy it is to install the software.
Just type in "emerge apache" (for example) and it will automatically download all the needed dependencies.
I played around with red hat and it was apain to install software, even using the gui.
Also, red hat is going comercial. They are no longer providing red hat for free downloads. Fedora is kind of taking the free version of red hat's place.
Just my 2 cents,
