Neither is inherently "better" or "worse." They are both fully capable of being used as LiveCDs, and can run the same applications. Xubuntu's system requirements are somewhat lighter than Kubuntu's and thus may run better on older computers. Kubuntu contains more visually appealing "eye-candy" and an arguably more feature-filled desktop.
The following are designed primarily or entirely to function as LiveCD distributions: * Knoppix * Damn Small Linux * Feather Linux * Slax * Archie The following have a LiveCD component, but were designed more for installation to a hard drive: * Ubuntu (and derivatives like Kubuntu and Xubuntu) * Freespire * PCLinuxOS * Fedora * Mandriva * Pardus

If I had to type all the Linux distros that exist, I'd be here for a long time. Common ones are: Ubuntu (and derivatives such as Kubuntu, Xubuntu, Lubuntu, etc.) openSUSE Fedora Debian Mint
Xubuntu was created on 2006-06-23.
Kubuntu was created on 2005-04-08.
Kubuntu is developed by Canonical, Ltd, the developers of Ubuntu.
The best known as a LiveCD (as opposed to being the most popular with a LiveCD available) is Knoppix.
A LiveCD is a bootable CD that provides a fully functional operating system with no need for installation.
Xubuntu is a Linux distribution based upon Ubuntu. It uses a lighter desktop environment, known as Xfce. Appearance and usage-wise, it differs little from Ubuntu, and can run the same programs. This makes it a better choice for some older computers.
This is generally a matter of preference based on what user interface you prefer (KDE in Kubuntu, or GNOME in Ubuntu). They are both produced by the same company, although some believe the Ubuntu distribution receives more attention and polish.
Ubuntu includes Mozilla Firefox by default. The web browser for Kubuntu is Konqueror.
Most of the popular Linux distributions these days have a LiveCD portion, including Ubuntu, PCLinuxOS, and even Gentoo. The most popular known specifically for LiveCD functionality is probably Knoppix.
