KDE4 is not a 'more current' version of KDE3 (in the same sense as KDE3 is more modern version of KDE2 and KDE2 is more modern version of KDE1). I'd say it is not KDE at all.

I am one of those people. But describing what features missing in Gnome compared to KDE3  would be much quicker. I dont think you wish to see here hundreeds of pages describing differences between KDE4 and KDE3 which make it unusable.
