RedHat has 7.2 out.  I just burned the CDs.  In the release email I got, they 
tout Gnome and Nautalus but there is no mention of KDE.  I know KDE is in 
there but they are obviously pushing Gnome.

SuSE is very KDE "centered."  I assume other distros may be "centered" on 
some other window manager/desktop environment.

Question: Is it better/more reliable/more supported to run the 
distro-preferred desktop or does it not really matter?

To ask it another way: Is it true that, for example, if I really like KDE, I 
should use SuSE because SuSE will be "better" integrated with KDE and, 
conversely, if I really like RedHat I should use Gnome since they will 
support Gnome better?  That it is better to use the "matching" distro and 
desktop pair?
