"PCBSD
By the name, it's obvious PCBSD isn't a Linux distro. This FreeBSD
based distro is regarded as a very friendly distro, containing a
unique package manager called PBI, which provides a functionality
much like installing an .exe file in Windows. This functionality
removes dependency issues and makes installing much more simpler.
FreeBSD has recently moved to using KDE4 and provides a very
friendly experience. If the user prefers using ports as it's
package manager instead of PBI, it is possible by typing some
commands in the terminal, converting PCBSD into a standard FreeBSD
rolling distro.
"Fedora
Fedora is a RPM RedHat sponsored distro, which has an objective of
only being made of open-source software, including it's main
repositories only contains packages which are at Fedora's
open-source standards. Fedora is normally considered to be a Gnome
distro, but it also has a KDE4 distro available as well called the
Fedora 10 KDE Desktop Edition."
