Debian’s preinstalled software on some desktops is one of my main problems with the distro and one of the reasons I hesitate to recommend it to newbies, so I like the idea behind something like this or SpiralLinux, but I wouldn’t use either distro myself, because I find that the more a distro deviates from upstream and adds its own configurations, the harder it is to troubleshoot issues or configure them the way I like.
As for Xebian, I don’t see the point of trying to make Debian Sid easier to install. It’s a development release, guaranteed to have many bugs, and not really suitable for the average user. If you can’t install and “declutter” sid yourself, it’s better to be using the latest stable or even testing release.
