for LAMP fedora is rock solid.As for KDE vs Gnome....it depends on the user....there are power users who prefer to do most of their stuff from commandline, desktop wont matter, and Gnome wud suite such people better as it hogs less resources.For a normal user who wants all the eye candy and stuff, KDE still rules. In fact I still use KDE even 4 yrs after switchin to Linux.Even though I use commandline for many of my tasks , I prefer KDE. So its really down to personal prefs. Also application support is better now in KDE than Gnome (I now we can run apps irrespective of the desktop ..but i am talkin abt native apps)
