well, as for Ubuntu ... It is not that crappy, as it could seem from the first try. There are various versions (is version a good word?), including Ubuntu (Gnome based), KUbuntu (KDE based), Edubuntu (never tried). Yes, it is much worse than Debian for experienced users, but it seems to me, that it is one of the most popular Linux distros for begginers in Finland.
As for me, I think that Debian is great, however I still use Slackware. (used it for the last 5 (?) years). First experience was with RedHat, but I think that if you are more or less know what you are doing, you should use Slack. Others are just trying to make it more user-friendly (read: windows-like). IMHO, it's not bad, cause it brings more ppl into the commmmunity.
