Yeah, but Xfce also has fewer features and less polish. e.g. I have had regular problems with connecting multiple monitors or from restarting a monitor etc. KDE

Yeah, but Xfce also has fewer features and less polish. e.g. I have had regular problems with connecting multiple monitors or from restarting a monitor etc. KDE also on the other hand has more useful applications pre-loaded (for minimalists it might be "bloat") but like others said, if you have the disk and memory why not get a more useable DE.
