depending on who you read GNOME is worse, slightly better or about the same. 
Note "window manager" is exactly that -- the thing which draws borders around
windows and helps you interact with them.  You can run pretty much any wm you
want and still use KDE/GNOME apps.  Some wms interoperate better though.

As an experiment load up just a window manager and run the KDE app(s) you are
most interested in.  I use blackbox on my laptop and run one or two kde apps,
mostly konqueror.

sorry, someone more familiar with running the full KDE suite will have to
comment on this.  What you might be seeing is a threaded application which ps
shows as multiple instances of the same app.
