"kde4 is quite powerful, arguably less resource intensive, and in full development. plasma is a wonderful desktop manager, and seems to have loads of new features in 4.4 (out feb 9th), not to mention kopete 1.0 (finally). kate/kdevelop(beta) is also rocking, amarok2 is getting itself straight, dolphin is a wodnerful filemanager (but konqueror is here too). and kde4.5 promises the kontact 2, atop akonadi (personal data center) and integrating akregator, kmail, kontact, etc.
not to mention the theme layer, kde-lookdotorg is full of new stuff every day. (""get new stuff"" works wonderfully in archlinux kde4.3.4, and it seems to be improving as well).
btw, the egyptian theme for kpatience makes it the most beautiful card game i played on the pc."
