KDE? yes it WAS better then Gnome, as long as it WAS KDE.KDE 3, that is.
now, KDE (4) is just another v!$t0 failure forcing the users to upgrade their hardware ): CPU & Graphic card & disks... sounds familiar? yeah, right... v!$t0 :( and unfortunately, they are still a VERY long way from se7en :@
the solution? well, openSUSE 11.3, for a couple more years as it is still possible to install KDE 3.5.10 on openSUSE 11.3
openSUSE (and other distros) are more then just "different skins"; that may apply to the "XYbuntu" crap where indeed all the fuss is about the interface.
other distributions distinguish themselves more, like:
- update mechanism (dpkg or apt-get for Debian and XYbuntu crap, rpm / yum for RedHat & Co (fedora and quite few more) or YaST for openSUSE).
- configuration tools; most distro simply use whatever comes w/ the interface, making it difficult to find things if you switch from one to the other (Gnome to KDE or want to try out LXDE aso.); openSUSE chose, nearly 15 yrs ago to create an interface that allows to manage the system centrally and more uniformly no matter what interface you use (even from the command line, if the graphical environment doesn't want to start!)
openSUSE also comes w/ a broad community that is likely to have already come across any situation you will face & published the solution on the site's wiki. there is also a HCL (Hw Compatibility List) that easily gives instructions to get your hardware working if it doesn't out of the box (especially true for wireless cards & web-cams).
one of the key feature of openSUSE is that even though it is open source it is backed by a commercial company (Novell) which provides strong support to its open source "branch".
and Novell's new owner, Attachmate Corp seems to want to continue this approach :)
choosing a distro is a matter of personal preferences and even though i have long ago started using virtual machines to try out new releases of other distros, i still have to find one that makes me feel like i even want to go thru the trouble of installing it on a spare partition on my PC.
let's hope that by the time 11.3 reaches its end-of-support (some 2 yrs) KDE4 will have matured some and have become usable...
'til then, i'll stay w/ 11.3 under KDE 3.5.10 and for any new user, especially coming from M$ LostDOS Gnome may be a valid alternative (also on 11.4 to be released soon) as it tries to give (ex-)windoooooz users some familiarity and simplify away the Linux hard chores)
good luck in your Linux experience, whichever distro or interface you may choose.
